A big issue for platforms like farcaster is that it took me 4 years and a ton of effort to build up an audience and following on twitter.

The ability to port that network over to farcaster is crucial for ppl to fully migrate to this app.

It’s just too much work to go through again for an app with very similar functionality to where your network already exists. 

I feel like it’s just too difficult to scale up the user base effectively without the ability to port over easily.

The issue is your audience won't port over in terms of DAU / habit. So at best you get 10-20%. And Elon has shut down the official follow APIs, so any way you try to export would be clunky, have low uptake.

wdym shut down the follow API ?
