Farcaster

1. Warpcast competitor either works as: open source project, small team like Supercast or once the protocol is 2 orders of magnitude larger

2. Definitely an opportunity

3. I don't think that's significant friction for most users right now. At scale, sure.

4. PWAs are fine if your use case is 1x a week or 1x a month. Not daily.

100x sounds about right as the threshold for non-trading/general purpose clients to work as businesses
