I was wondering if there's a site out there that gives statistics towards the percentage of sites that use jQuery UI? (Note I'm not looking for the actual number of sites nor jQuery itself ... just jQuery UI).
I rolled a custom version of jQuery UI that only uses about one-third of the widgets, and I'm trying to decide whether to locally host the smaller version, or hotlink to the full thing off of Google's CDN. Obviously it would make sense to use the CDN if there's a very good chance it's already been downloaded, but, if not, the file will be 3-4X the size for no reason.
