I’d love a federated Strava replacement. Unfortunately I don’t believe that the AT Protocol supports private or limited visibility posts yet, which I think is a pretty key feature for Strava’s use case.
Once atproto has first party support for private records I'm definitely expecting a massive increase in interest. It would open so many doors and is probably the main thing holding back many potential use cases as of now.
Also a big fan of directly running my projects on VPCs. I do a lot of development on my Linux machine so I really enjoy not having any substantial differences between my local and deployed environments.
