Well, I started out with Wordpress, but I've had a lot of people tell me that Blogger is better for commenting and also for SEO, so I'm switching over. Luckily, I didn't have much content on Wordpress -- as in, nothing except one introductory post, so it wasn't as if I had much to lose. I've also heard it's easier to customize your blog on Blogger, so we'll see how that goes.
