AP was noted in the Sports Illustrated NFL Preview Issue this week as one of the Top 4 fan sites. Its the same poll as they have online.
Vote for AP here. You'll more than likely have to turn off pop-up blockers.
I don't want to rag on the other sites listed but if you want real writing and commentary (not just RSS news feeds) on the front page, a site that is as much mine as it is OURS (no anonymous webmaster here) and a guaranteed stream of just good Chiefs reading (instead of once a month posting), vote for Arrowhead Pride.
