I hated these sort of things when i was at Uni. For my first year we used blackboard but they migrated to something new my second year, I forget what its called of hand. Either way they both sucked.
I also hated them simply for the fact that teachers either a) under used them (or used them improperly i should say) or b) over used them.
I really hated teachers who thought this was a great excuse to give us extra long tests all the time for out of class work. Especially when you're just expected to check it everyday for new stuff and they don't bother to tell you its there.
What if I'm a Snowstorm burning
What if I'm a world unturning.
