I remember two downturns:

• 2012 stagnation of development about that time when the other co-founder was fired or something

“Sounds interesting. Reading! Not likely to do anything like this soon as we are underfunded and just getting going. But it sounds interesting! […] Ok.

I’m reading up on ActivityPub to see if there’s a way to support it natively. If real tools are being built that I can interoperate with, that’s a clear win all around.”
