One thing I really miss on micro.blog is a Like button.
It’s a very concise message you can send, basically saying “I saw this” and thought it was notable.
Another thing I miss is Cmd-I italicizing the selection. I do a lot of writing in GitHub and their Markdown editor has a lot of conveniences like this.
It is also possible to have a Wizzy editor that generates Markdown. There’s Medium-editor project that supports that. If you want pointers, let me know.
I’m starting to check this every so often, so there’s a bit of addiction happening here. ;-)
