Aaron, of Aaron's CC, is now taking nominations for the suit of spades...
You should nominate a blog that focuses mainly on one subject & it must be a blog that has comments enabled. (You put nominations in the comments, but beware -if you add links it gets eaten as SPAM).
There are many great blogs in this category, but I have nominated:
The Anti Idiotarian Rottweiler (because they ROCK and because they don't know I exist yet!!! LOL)
My dear friend Kat of The Middle Ground. You can't talk about informative blogging and not have Kat on the list! (If you haven't checked out her new blog template -go do so...she designed it herself!)
