Because in university it's their job to cram your head full of the complicated stuff that you wouldn't otherwise bother learning on your own. Seriously, I have a friend who's working for the government over here and all he uses is VB.NET and ASP.
Of course, all these comp sci dudes in university are hoping to be programming NASA's space shuttles and your futuristic refrigerators, so of course VB is of no use to them (unless space shuttles run Windows).
**EDIT: Of course, this is WAY off topic. If anyone wants to start a VB war, I suppose it should be in another thread.
