I've heard of UoP (hard not to) but hadn't really considered them before. A compressed schedule certainly has it's benefits: receiving my degree before I'm 80 is nice. :-)
One of the things that I enjoyed while going to school was the interaction w/ fellow students. If I was having a hard time wrapping my head around a calculus problem I could consult w/ other students to help me understand. How does UoP address this? Are there chat rooms, mailing lists, etc? IMHO There is absolutely nothing wrong with distance learning, but you do lose out on the personal relationship side.
