An impressive collection of search data! Although for your "many eyes" aggregations I'm curious why you didn't make the terms case-insensitive so that "beauty" and "Beauty" wouldn't be treated separately. Ideally they'd be combined as they are essentially the same search.

Analyzing the terms to find "alike" searches (e.g. combine "television" and "tv") could also be interesting. So interesting, in fact that I'll do it real quick for those top 50 Ad*Access terms. It turns out the ordering becomes significantly different:
