Microblog is Twitter-like, normally plain-text only, normally limited in characters, no titles, no summaries because unnecessary for not even 1,000 characters per post. Also, conversations/threads consist of posts, posts and more posts that are loosely connected via mentions.

Blog is like WordPress or Blogger or Medium. With titles, with summaries, no character limits and the whole shebang of formatting.

Headlines

in

multiple

levels,

bold type, italics, code,

• bullet-point lists,

1. numbered lists,

images embedded in-line within the post (with text above the image and more text below the image), nicely embedded links instead of URLs in plain sight and so on. Also, conversations consist of exactly one (1) post, and replies are comments that aren't posts and work differently from posts.

@5teverin0 @SharkAttak The lines kinda blur in some places, but mostly just no max post length, text formatting, and a layout that more resembles a blog as apposed to a twitter profile (tags/categories, about page, that sort of stuff). You also usually get a domain or sub domain (example.com or user.example.com respectively) instead of just a handle (e.g. example.com/@user) so that it's easier to use as an independent website.
