>>Anybody want to share what they think is ringing bells for Yahoo?

There are a few things that definitely seem to wind their clock, just plain old garden-variety optimization - it's a matter of how and where keywords and phrases are used.

>>Is Yahoo filtering scraper sites?

I'm still seeing some scraper sites, though they're a little less prevalent; one I've seen for a while even still out there with the scraped content in an iframe. But they're not in a space that would be prone to hand checks unless attention was drawn to the particular searches, which apparently hasn't been done.

There have been a lot of reports about subdomain "illegitimacy," with some from the same party (or parties) taking up the whole beginning of the SERPs - including blog sites. I know it's the new YST, but the old Inktomi had a thing about subdomains. Mind you this is outdated on a few points, but gives some historical view worth looking at

What I'm just starting to look at is whether the percentage or proportion of links coming from the same IP has any bearing.
