Sick, I get tons of more interesting content while being with a Mastodon instance I trust, a nice FOSS client to explore the content, and keep my privacy! If this actually bothered me, I could simply click the three dots and block the instance, so surely that shouldn’t be a big deal, right?
Being in control of who sees my post. Lemmy still lacks more granular post visibility like Mastodon does. If I restrict a message to followers on Mastodon, I know just they would see it, and so would their current instances which are much smaller and fragmented. Compared that to any social media where that’s going to easily be tracked on both sides. Federating with threads doesn’t change this. Also as you said, lack of analytics is nice. Privacy could definitely be improved though. Mastodon direct messaging is still weird and really should use e2ee.
