Anyone used the Oreilly school?

By accident I noticed that the well known publisher O'reilly have set up web based training. Now I'm old school and get everything from man pages, books, and the Internet, but I'm wondering if I should try it. I wrote some big stuff in perl and python years ago and some small stuff in C but I'm pretty rusty since I spend all my time doing system and network admin these days.

Has anyone here used the Oreilly school? Any good or bad experiences?
