I'm building Shpong[0] with a fellow HNer. It's a publicly accessible Matrix server with reddit-like features. Not quite ready yet, but almost there...
I'm curious about any comparisons you did, or if there were technical concerns with Lemmy or Matrix.
(I hope this question comes across as genuinely curious, I don't mean to snark at your project! I just like reading about decisions to choose one thing vs another)
I'm just more familiar with the Matrix protocol, having built several projects on it. Activitypub is pretty cool though and I'm working on AP support, so Shpong should be able to interface with Lemmy in the near future!
