oooh, aha! Thanks!
I really can't see how these are supposed to be acceptable, since they're so resembling the actual content, IMHO they're even less 'acceptable' than, say, ads on the side that are 1) elsewhere, not right where I expect content 2) clearly identifiable as ads without even looking at them. So that they're much more easy to ignore. Ads are just a pest.
Well anyway, thanks a lot for saving my startpage
