One thing I wish we had that we used to have: blog-only search engines. You could go and search for a hash tag. Or for links to your blog or elsewhere. Or for keywords. Etc.
Here’s a provisional thought (all thoughts on a blog are provisional) — to read a good blog is to watch a writer get a little bit better, day after day, at writing the truth.
Micro.blog rewinds us to 2005 (or pick your year) — but, also, it has learned the lesson that people really like a timeline of short posts. People like being able to write and reply easily to other people.
