Setting up new blog?

I am thinking of building another blog (I know, don't I have enough). But I really feel strongly about setting up two additional blogs. Those two would be niche blogs, as in I will only be speaking of something specific rather than the mixed bag I have in my other sites.

Before I set them up though, I must consider a couple of things. Do I self host them? If so, I need to check out good webhosting plans and also decide if I'd sign up for a new one, or just add on to the existing one I have for my other sites. I'm even thinking of setting it up in Blogger and just signing up for a domain name.

There are really a lot of things to consider before setting up a blog or a website and deciding on webhosting is definitely one of the most important steps, next to picking out domain names.
