Having tried all three, its a stark difference in how much more social Lemmy is comparatively. Its not even close. Almost all posts I've encountered on lemmy have interaction; whereas, more often than not, posts on the other two platforms have no interaction. Wonder what the driving factor is behind this difference?
The blog style format (post + threaded comments) is a lot more inviting to a conversational style than microblogging. Some Masto instances have very open post character counts but some are much more limiting - as are Bluesky and Xitter. If you're not able to explain your point clearly it hampers the ability to have a decent conversation about it.
explain your point clearly with unittests. Then we are talking.
Prove it's true otherwise it's just conjecture. A missive. A random thought, or G'd forbid, good intentions.
I'll save you the time: "It's just conjecture".
