Geez. Give the poster a break! What difference will it make if there are 7432 blogs pushing credit cards or 7433 blogs pushing credit cards!?
My advice to the OP: take a look at the Roll Call thread:
http://www.flyertalk.com/forum/exter...resources.html and take a look at the various platforms employed. Do a little research on the ones you like.
When you get it up, be sure to add it to the roll call wiki!
Good luck with your venture.
