@zeus - it seems the only benefit is for the sites taking up the entire page. Coincidentally, those sites are never mom & pop sites, they are always well funded sites with an army of bad writers. Topic overkill on a per domain basis and domain crowding is just another form of spam. Why can't Google see this?
BTW, yesterday was this highest traffic day in over a month, but not the highest converting. Mediocre quality at best.
