Yeah, I think a cool thing about blogging is that there are so many distinct tastes that there's a lot of room for different writing styles, and you can find people who like your style.

When bloggers say, "I don't want to write about topic X because person Y already wrote the definitive post about it," I say, "However good the existing article is, there will still be people that prefer yours." Even if the other person is smarter, more knowledgeable, whatever, you're going to explain it in your own way, and that's going to resonate with a distinct set of people than any other article out there.
