According to this website, there are certain types of blogs that are most popular. They are not in any particular order (as in most popular first). But here's a selection of them:
Fashion blogs: I know almost nothing about fashion. I'm more of a jeans and T-shirt kind of guy.
Food blogs: Anyone who knows me, knows I like food. But I can't see writing about it much except maybe restaurant reviews. But I don't go to that many restaurants, anyway. I live in a small town and the selection is limited (we do have two McDonalds).
Travel blogs: Due to health reasons, I can't really travel much. And I hate flying. If I can't drive there in one day, I don't want to go.
Music blogs: I've talked about music. But I don't listen to new music (anything past the early 1990s). So unless I rehash what I love about 70s rock music, I'm not going to fill a whole blog about it. And I don't know a lot about music. Just what I like but not the details of how it is made.
Fitness blogs: Har dee har har.
DIY blogs: This has to do with do it yourself (DIY) projects mostly around the home. Me, I can barely pound a nail straight. If I need something done around the house, I call a handyman or contractor.
Political blogs: I used to have a blog that was mostly political. I avoid politics here because why alienate half your audience. As Michael Jordon said (and I paraphrase), "Republicans buy sneakers too."
There's lots more. Probably this blog comes closest to being a "personal blog." I know there are blogs out there that get thousands of page views a day. I feel lucky if I get thirty.
