Beats me how the source code be different than the output . Are you using some caching mechanism for your site or something? Even then it still wouldn't make sense.
I do use cache ( a lot of it ). I repeated your excercise and saw the differnce in soruce and display, then I manually cleared the cache, checked the page and the source again and they matched Also, there should have been 5 ads showing and there was only 4. I don't know how long this has been going because I never check as long as the site validates and the weight holds.
Yeah I did notice the empty space between two pipes but didn't think much of it... Phat chance this stuff is what keeps you unvalidated.
argh my weight still hasn't come back keeps ever so slowly dropping I'm attempting more deep links now in my campaign seems to have aided some of my other sites for increasing the pages indexed. hope it increases again for my osCommerce site went from 26k to 5k
