First of all I would like to thank you for the awesome Jetpack Plugin, it's really great.
But I can't understand why you dont compress / minify the Scripts and CSS in the Jetpack Plugin. You can really speed up the Blogs with compressed files, why you don't do that?
The next thing I noticed is that jetpack include js files of deactivated functions e.g. I've disabled cycle Plugin but in the source of my webpage is a jquery.cycle.js.
