Well, for a blog sort of website, usually people go with
[Their name] + 's + place + .com (sally'splace.com, etc)
However, if you're looking for something unique, try to mix it up a little. Use a name, and add some catchy ending like
- dungeonoffear.com
- theevilbakery.com
- skid-row.com
- michaelboltonfanclub.com
You don't want to make the website name too long, or people will often forget. Try mixing up words with names, and i'm sure you'll find something that works.
