Because it has not been posted and it is a fun read?...I know the left wing Kos blogger did get paid and even raised money for candidates on his site..
Now if only we FR bloggers could make a full-time living on here - we'd have the perfect home-based business. <sigh I'd love to get paid for posting as well helping out the conservative cause and so I suspect would almost every one on here. The earning potential is unlimited.
