Has Reddit usage gone down in the past few weeks since the API change or has it returned to normal?

Yup, you’re right I wasn’t even thinking about that.

He mentioned that he’s on Twitter and Mastodon in his farewell post. Maybe he’ll create a 3rd party app for one of those?

I gave Mastodon a small chance a couple weeks ago and just hopped on Lemmy today and I can already tell (at least as of right now) I prefer Lemmy as a platform. I’ll definitely give Mastodon another chance but I just couldn’t really get into it. I think I agree with you on the fact that the content seems to federate better on Lemmy.
