Sabine Hossenfelder gives some useful advice about "Should you write a science blog?".
Advice #8: Don’t be afraid of your readers.
If everybody would like what you write, somebody would hate it just because everybody likes it, so it’s futile. If I’ve learned one thing from blogging, it’s that misunderstandings are unavoidable. They’re part of the process and that’s a two-way process. Just don’t take hits frontally, use their momentum. That misunderstanding really makes a good topic for your next blogpost, no?
I also like this: "But don’t think you actually have to be a good writer. Because most likely your readers aren’t good readers either, which is only fair."
