MyWeb from Yahoo now include two extra links in the search results pages (see below)



The two extra buttons are "Save" and "Block" seem to appear for all results whether you have signed up for MyWeb or not. I'm wondering whether Yahoo will plan to give some extra ranking to sites that many users have saved, likewise will a site fall in the rankings if many users block a particular site? I think there could be serious gaming going on if this were the case to artificially increase ranking or decrease a competitors site.
