@qyliss A few things! Awoo.space has a different federation policy; while mastodon.social has a blacklist approach (federate by default, blacklist known bad actors), awoo.space has a whitelist of instances it federates to. The intent is to focus on safety and privacy first and foremost.
@qyliss Similarly, awoo.space is intentionally and proactively moderated in a way that mastodon.social is not. You can find information about that here: https://awoo.space/about/more
@qyliss Finally, mastodon.social is pretty much constantly updated, and since there isn't a staging server, many changes are tested live. awoo.space updates periodically, so it lags on updates but also tends to be more stable as a result.
@qyliss That said, private posts have a weird interaction with federation right now, which limits essentially all non-mastodon.social instances. It's something that will change, but is worth considering right now.
@qyliss Privacy, safety, and a constant rollout of untested features are my biggest complaints with twitter, so awoo.space's approach fits my needs more than mastodon.social does. Other people feel differently, and that's totally valid!
