How I grew @prov_pizza 3650% over the last month.

This is me trying to build in public like @thisiskp_ and being transparent like @jackbutcher.

A visual thread. 👇🍕

1/ The secret towards getting these gains? Start from zero.

The stats after 4 weeks:

0 —> 77.4K Impressions
0 —> 6,130 Profile visits
0 —> 490 Likes
2 —> 73 Followers, sorry for the bait ;)

Here are some of my key learnings. 👇

2/ @jamierusso taught me to remix the content of others.

With only 9 followers I added some pizza sauce to Jamie’s content.

It got me over 4K impressions on a single tweet.

3/ The key to a good remix: add value.

With @prov_pizza I tried to add:

- Another perspective.
- Humor.
- Pizza. This usually does the trick ;

4/ Remixes were a pitfall too.

I was tempted to remix anything from anyone I found interesting, because it seemed to work.

@foundbryan taught me to stick to my niche.

Incoming rant.

I'm pressing the "tweet" button as I type, and I'm typing as I think, so there's every possibility that this will drift into tangents and/or nowhere. Of course, that's true pretty much every time I start threading.

I know diddly-squat about physiology.

Friends and family who *do* know anything about physiology regularly mock my (apparently bizarre) theories of how bodies work.

I am not a trustworthy narrator when it comes to things like How Vaccines Work.

I know diddly-squat about epidemiology.

Unlike physiology, where I am firmly in the domain of Messrs. Dunning and Kruger, I've read enough about the subject to understand how little I know.

This is a complicated subject, where obvious truths are seldom either obvious or true.

I also know diddly-squat about public health policy.

Public *transportation* policy is way more in my wheelhouse. But this at least lets me make some useful analogies.

…I mentioned digressions? Yeah, I just started to write a very long digression about public transportation paradoxes, and it was taking away from the point I wanted to make.

It is past due time we talk about microaggressions on interviews (a thread #MedTwitter #AcademicTwitter):

First, microaggressions are harmful! Despite their name, they signal “you don’t belong here” to marginalized groups.

Second, interview days are already nerve-wrecking.

One comment or experience has the ability to undermine an interview day. Applicants may not have the ability to report immediately and anonymously or may fear retribution for doing so. Interview day microaggressions put applicants in an awkward spot in addition to the harm.

They are also not rare experiences. As a Black woman, I have experienced them at multiple institutions and different levels. I’m sharing my stories as examples of what happens, but I have no doubt there are many others, even within your institution, that need to be responded to.

College: I had an in-person panel interview for a full-tuition scholarship. One POC on the panel repeatedly asked, “where are you from?” I was 17 and eager to please, but also knew I didn’t have to share that my ancestors were traumatized thru slavery. I got flustered and bombed.

Med school: A diversity website wrote, we need more physicians of color because they are more likely to serve in underserved communities. While true, the reason we need more representation in medicine is because minoritized groups have been kept out. PERIOD. I didn’t apply there.

With all that's going on in the world, I wanted to introduce you all to the best thread on Twitter.

If you haven't heard of 'Eastbourne' and the old people that live in our town, get ready.

First up, it's the time when it kicked off between Edith and Dorothy.

I wrote a lot of pieces in 2020! As we close out the year, I want to share a short list of my favorites. (thread)

In March, while we all watched in horror as the Trump administration botched the initial response to the pandemic, I wrote for @Independent about the bizarre and unjust access many healthy celebrities gained to COVID tests, which were quite scarce.

In April, when it was apparent Joe Biden was on his way to winning the nomination, I wrote for @washingtonpost on why progressives should have optimism about a Biden White House.

In June, the Supreme Court issued a landmark ruling affirming employment protections for LGBTQ people. It's cause for celebration, but as I wrote for @Cosmopolitan: this is a mere fraction of LGBTQ equality. We *must* pass the Equality Act.

That same month brought controversy as J.K. Rowling seemed to be completely unaware of the violence and discrimination faced by trans and non-binary people. So, I wrote about my own experiences in that vein for @USAToday in the hopes of educating folks:

1/OK, data mystery time.

This New York Times feature shows China with a Gini Index of less than 30, which would make it more equal than Canada, France, or the Netherlands. https://t.co/g3Sv6DZTDE

That's weird. Income inequality in China is legendary.

Let's check this number.

2/The New York Times cites the World Bank's recent report, "Fair Progress? Economic Mobility across Generations Around the World".

The report is available here:

3/The World Bank report has a graph in which it appears to show the same value for China's Gini - under 0.3.

The graph cites the World Development Indicators as its source for the income inequality data.

4/The World Development Indicators are available at the World Bank's website.

Here's the Gini index: https://t.co/MvylQzpX6A

It looks as if the latest estimate for China's Gini is 42.2.

That estimate is from 2012.

5/A Gini of 42.2 would put China in the same neighborhood as the U.S., whose Gini was estimated at 41 in 2013.

I can't find the <30 number anywhere. The only other estimate in the tables for China is from 2008, when it was estimated at 42.8.

Santkumaras-The four adorable kids of the Universe.

The Kumaras r the four sages who roam the Universe as children from the Puranic texts of Hinduism named,Sanaka, Sanatana,Sanandana& Sanatkumara.They r described as the first mind-born creations &sons of the creator God Brahma.

Brahma,who had received the knowledge of Puranas from the Universal being(God Himself), imbibed this to his 4 Kumaras.
Sanat Kumaras then taught the Puranas to Narada.Narada transmitted it to Krishna Dwaipayana who in turn scripted them in monumental epic documents of 18 Puranas.

The Vishnu Purana is recorded in two parts,the Vishnu Purana & Naradiya Purana.The teachings of Sanaka of the Kumara brothers r contained in the Naradiya Purana which is also divided in two parts, the first part containing the teachings of Sanaka &second part,teachings of others.

Born from Brahma's mind,4 Kumars took lifelong vows of celibacy against their father's wishes.They r said to wander throughout materialistic &spiritualistic universe without any desire but with the aim to teach.All 4 brothers studied Vedas from their Childhood&travelled together.

The Bhagwata Purana lists the Kumaras among the 12 Mahajanas(great devotees or bhaktas) who although being eternally liberated souls from birth, still became attracted to the devotional service of Vishnu from their already enlightened state.

UNTOLD STORY OF QUEEN BHAVASHANKARI OF BENGAL - A 🧵u must read

Know the role of Naga Sadhus

PART-1

One of the most underrated empires to ever grace India is the kingdom of Bhurshut from central Bengal.

1/

A medieval powerhouse this kingdom stood firm against the Pathan invasion from Orissa twice, and with each time devastating the enemy forces.

Along with this, we also have to note that this was the time when the empire was under the reign of a widowed queen named Bhavashankari.

She wasn’t even born in a royal family and yet she achieved what most of the kings couldn’t do

This begs the question, why does no one remember this great kingdom?

3/

Bhurshut empire thrived from 15th century till late 18th century as an independent kingdom while acting as tributary state with full autonomy.

4/

What’s even more puzzling is that no one knows about the great queen Bhavanshakari who thrashed the Pathans single handedly without the aid of their allies.

The best way to know if people like your product is NOT:

- Have a lot of emails in the waiting list
- Become #1 on PH
- Become #1 of HN or Reddit
- Have people that saing "I'll pay"
- Have a lot of free users

The best way to know if they're actually pay for it.

The only thing that matters is your product providing a value, and you can't know this until people will pay money for it.

We can have a first signal of a product/market fit after the launch by check how many sales we've got in the first 24h. Some scale:

200+ This has a high potential.
100+: This has a potential.
50+: Some people need it.
10+: People almost don't need it.
0+: People don't need it.

This is for a single time payment product. For a subscription probably it should be less because people hate subscription.

And obviously, you should have a lot of traffic like 3-5k+.

Here is a stat for my products (macOS apps) for the first 24h after the launch:

(An extract from Field Marshal Sam Manekshaw, Soldiering with Dignity)

The man eventually destined to be free India's first Field Marshal was born on 3rd April 1914 at Amritsar. How did a Parsi couple settle for the holy city of the Sikhs? I once asked him and was told that in+
