Which got me thinking about how useful an offline version of google would be. Unrealistic or impossible? What if you could download a "Google for JavaScript" where, based on lots of javascript developers query, you downloaded a cached version of the results and the websites? I.e. It's easy to get the top 100000 queries containing javascript; you get the top20 links for every queries, you download those websites and compress that. I don't know how big that'd be. I'm sure it'd be possible to use that in a clever way and make it small enough to be easy downloadable. A couple of gigs.. what's that for today?
