Confused? So was I at first. Here's the trick, try reading it vertically. You'll find Poli (political), Freq (frequency), Spec (specific), Pers (personal), Rant (just that, rant). Everyone's BlogPrint has these terms, but the letters colored on your BlogPrint tell what kind of blog you have. My blog is semi-political, with semi-frequent posts, it's non-specific (I have a wide range of topics), it's semi-personal, and I don't rant very much. This is a neat idea, but honestly, it will probably only work if a majority of bloggers were to implement it. Still interesting though. Give it a try.
Note: I'd like to give a warm welcome to my current renter in the Rent My Blog campaign. If you look to the right, you'll see it in the sidebar. My current renter is Full Metal Photographer, so give him a visit and say hey!
