Earlier today, news broke that Google's new index would launch soon. The news was simultaneously exciting and disconcerting since most SEOs and search marketers are in full-fledged holiday mode, and boy, would this disrupt things.

Caffeine will still be rolled out to one data center, which Cutts said will affect a small percentage of searchers.
