In no particular order my favorite agent blogs are: Bookends, Nathan Bransford - Curtis Brown, and Kristin Nelson - Pub Rants. Consistent, funny and full of all sorts of win and halarity. I definetly fancy these blogs the most.
Here is the info you are seeking. It isn't necessary to post the same question so many times. Once will do. FYI: there is a forum dedicated to asking questions about specific agents and agencies. Just click the link above.
Here's their website in case you want more info. I found them on AgentQuery and sent a query over the weekend, but haven't heard anything yet. They only have one novel sold that I can see, but they're only a couple years old.
