Cuil Whipped. Cuil has dropped to almost zero usage share.

This is sort of silly. Cuil never got above "almost zero" usage share. There was a horribly ill-timed splash during launch which resulted in a lot of visits for a week or two--they were obviously way too early, since most Cuil searches are disappointments. So, none of those user stuck around.

Cuil was stillborn...it hasn't "dropped", because there was no room at the bottom for it to go lower. The chart just shows a spike like the one that happens to every new startup that gets some press.
