(this is my first post but I've been lurking for a while now)

No question about it. My main site took a major hit with 'Jagger' (nowhere to be found in a search for our main keywords) but as of this morning we've moved up in Yahoo AND MSN. On Yahoo we've been languishing on #23 but are now #9. On MSN we've moved from #30+ to #3 and seemed to have settled at #7.
