Looks like now Mbin, at least on mobile, mixes threads and microblog posts
(media.thebrainbin.org)
Must've been a recent change because somewhat frequently I'm using it on the go and just now it started appearing for me.
Also banners appear on the top of communities now too. =D
The posts that I've seen so far seem to be lacking context that's available when visiting the original on the home instance.
That is, these posts look like the first comment made by the OP in a thread below their main submission, but the main submission isn't visible.
Very disorienting. I hope there's a fix on the way.
Using Mastodon, it's a similar behavior there, and equally mildly annoying. Least bad in that sense imo is Misskey, as when the post is a reply, the one it replies to is partially loaded, though Misskey has so much visual noise it is disorienting in other ways.
