I post all my posts for the day in a block, so you'll see me post 3-6 things and be done. It's just easier for me. I post mainly educational content, so getting the posts out of the way all at once lets me just pop in during my breaks in the day to answer questions.
I don't think I'm annoying, and if anything, if you don't like my content, it keeps it in a relatively small range of your feed instead of it popping up multiple times. I figure I will annoy someone no matter what method I do it, so that's what I'm going to stick with. After 3 years of doing it, you've either blocked me or you're fine with it. 😁
