Globe of Blogs
Dang it! I can't remember who it was now who pointed me to this the other day, but I know it was a Rocky Top Brigadier. Anyway, thanks!
Globe of Blogs is a world-wide compendium of blogs and bloggers. Only 8000 blogs right now, but jeez...that's a lot of reading. GoB has a searchable database, though it's not perfect. Searching for "Tennessee" produced a whole lot of blogs, many in Memphis, but searching for "Memphis" only produced three. It is also searchable by a whole host of parameters: hobbies, politics, activist causes, lifestyle, etc.
Go sign up and then try it out. Very cool.
