Still building https://FastComments.com :) I'm planning on launching a desktop app for it soon with a combined forum. So you could have a community on something like discord, but all the chats are indexed and searchable through a web forum style interface as well. The desktop app is a native C++ app so no electron :)
I'm also working on launching https://watch.ly (network/fs sandbox with human in the loop for ai agents), mostly waiting for the entitlements from apple at this point...
oh and I launched https://dirtforever.net recently to keep Clubs going for Dirt Rally 2 without the EA servers. Learned about the egonet protocol and made a server.
