Show HN: Similarity, a spiritual successor to 2000s-era OkCupid

This is a side project I've been working on on-and-off (mostly off) since the 1990s. It should be pretty self-explanatory.

It's not vibe coded, though I lean pretty heavily on codex (mostly the $20/mo plan - not a lot of tokens burnt here). The stack is java, aws eb, neon postgres, and few cloudflare doodads. Basically designed to run by itself hands-off.

I'm working on some ideas to help with the chicken/egg problem but for now I have low expectations. It's cheap to run and I have a day job.

Would love feedback!
