It's tildes.net, the best overall description of my goals/values for the site is the announcement post: https://blog.tildes.net/announcing-tildes

It's not a competitor to Reddit in any meaningful sense though. If anything, my "target user" is almost the complete opposite of what Reddit prioritizes now. Calling it a competitor probably only makes sense if you still think of Reddit as the way it was like... 5-10 years ago.

It's invite-only to register, but feel free to email me at the address in the blog post and I'll send you one. (That offer's open to anyone else too.)
