For those of you that may (unfortunately) be bored over the holiday break, check out this link with a list of the top free online courses. You might be thinking that you *just* finished classes or don't want to do any coursework, but really these courses are test free and a great way to expand your range of knowledge so be sure to at least browse through some of the offerings. In particular, we have pointed faithful readers in this direction before, so this should not be new to regular readers.
And for those that aren't aware, be sure to also check out iTunes U via iTunes store. There are many free audio/video classes and podcasts.
