Ask HN: Advice for online cs degrees

I'm new in the industry and am loving it. I mostly do marketing work but can write some code and build rails apps. I've been taking classes on Udacity and am working on a fun final project (building a distributed python crawler and analyzing web data) and that should really help me learn a lot! I want to dive deeper into coding and improve.

The reason I want to get a degree is: 1) I sometimes lack structure/direction in my self teaching and would like more guidance. 2) I know that I lack some fundamental knowledge of cs and want to fill that. 3) A bit of self gratification.

I understand the usual advice of "If you really want to learn just start building" and am working in that direction, I just need a boost. So does anyone have advice on good programs to take? Also (revealing my ignorance) what is the difference between a CS and IT degree?

Thanks for any advice you guys give. I really appreciate it :)
