It makes me smile every time I notice IGListKit at work in Instagram. We put a lot of work into making and improving it. Proud to see it holding up 4 years later.

🧵 with some memories on how it was built:

At Instagram, product work slowed around the holidays, so we used the time to pay down tech debt. In winter 2014 I reviewed a +12k line refactor from UITableView to UICollectionView.

We recently dropped iOS 5 so we could use the new 6+ APIs without backwards compatibility.

That review taught me a lot about UICV: data sources should mutate in one place else risk out-of-sync exceptions, the first view layout may reloadData, sticky headers make good perf hard, and many more UICV tidbits

We used reloadData for everything and it worked, for the most part.

Except two things bugged the hell out of me:

1. No animated changes (duh)
2. Images could flicker and the like animation could cancel

I dug into the latter and learned that if you reloadData, every cell on screen gets reused. So even if nothing in the UI changes, you still reuse (or init) cells, bind data, set images, etc. that’s a lot of work!

Tomorrow, Zynga shuts down FarmVille on Facebook after 11 years. I wanted to share the story of how we created it and why it has played such an important role in the evolution of gaming. 1/x

The real innovation of FarmVille was in making games accessible to busy adults, giving them a place to invest and express themselves and be seen by people in their lives as creative. People thought of FarmVille as a sort of Etch-a-Sketch. 2/x

It was the first game at scale that leveraged big data, and almost everything inside the game was tested and optimized. FarmVille became a training ground for a generation of entrepreneurs and product managers. 3/x

In 2008, Happy Farm reached 20+ million daily active users, setting off a wave of competition from game developers, and numerous farming games began to hit the market. 4/x.

On February 6, 2009, FarmTown reached 1 million DAU on Facebook. Farm Town combined the moving maps from MyFarm with avatars in Zynga’s YoVille. I wrote the date on the wall, and said we need to count the days until we are in the market with our own game. 5/x

10 ridiculously simple tips I wish I knew about building an audience when I first started:

I mostly winged it 🤫

Let me share my lessons so you don't have to:

(a thread 🧵)

1/ Switch from being a consumer to a creator

If your default is opening social media and binging on updates from others, there's a problem. The world needs to know what YOU can offer, and I believe everyone can add value. So first, switch to intentionally becoming a creator.

2/ Start very small and build "Atomic habits"

Most beginner creators people aim too far high and crash. It never works for me. Instead choose tiny habits like 2 tweets a day in the morning. Or 1 video for Youtube. Or 1 short essay each day on Substack. Optimize for consistency.

3/ Pick one social platform to create and stick with it

What comes naturally to you? Writing your thoughts, choose Twitter. Editing interesting footage and layering a voice-over? Choose Youtube. Short essays? Choose Substack. Pick one and stick with it for at last 1 month.

4/ Find your niche

Don't focus on big bold segments with hundreds of active prolific creators already fishing. Find specific audiences and move towards them.

I was a no-code maker in 2018 so that niche came naturally. Later, I expanded to the community niche. Now #buildinpublic
