Gonna add on to this, if that's ok, because I think a lot of people don't know how to categorize their work:
- Shitposting? You're a comedian, a satirist.
- Long posts about other people's art? You're a critic (positive), a scholar.
- Long posts exploring ideas, society, and the world around you? You're an essayist, a philosopher.
- Can't get enough of sharing information about X topic? You're a scholar, an educator, a columnist.
- Just love collecting and sharing other people's stuff on your blog? Archivist, curator, collector.
- Just not sure where you fit? Babe, you're a blogger.
You don't have to be a professional (ie get paid) to be any of these things. You can claim the title without making any claims to the quality of your work. It's ok.
