I'm thinking about whether it makes more sense to include the http://code.jquery.com/jquery-latest.min.js file from the jQuery website, rather than hosting it on your own server, since 1st time visitors probably already have the jquery-latest.min.js from jquery.com downloaded and will be able to use a cached version of it, so page load time will be a bit faster.
Does anyone know how this works and want to share their thoughts? Do you think it is irrelevant or could there be some milliseconds to gain :) ?
