Thanks for picking up the plugin :-) - glad you like it (Tom - aka will's brother and another member of the Distilled team)

Google should give people the option:
1) (default) retain search records for 18 months
2) Retain no records
3) Grant ownership of the records to the user (non-exclusively licensed to Google), to be instantaneously and continuously published for as long as Google desires.

I think option 3 would be surprisingly popular, like a sort of twitter-cam of one's search box. It also levels the playing field: Googles gets the records forever, but then so does everyone else.

How many seconds before a Google/Twitter plug-in?
