The truncated posts are a great add! It makes the experience 10x better.
I like all of the new posting options but any chance they can be hidden behind an advanced menu. I think that would make the process easier to see.
I've also seen a bug on mobile where I post a buzz and then that buzz is seen as a comment on later buzzs I view even though it wasn't used wihtin that conversation. A refresh of hte page fixes it but seems there is something causing it to stick around after posting.
