what the heck is [electron] spin?

This is the kind of thing which drives me nuts in quantum mechanics.
What is this spin with values like h*/2?
electron doesn't rotate on its own axis, right? So what is the meaning of this angular momentum? I know only the I x W
why it behaves like angular momentum if it is not one?
and the misnomer spin totally trips me off.
Really if someone claims he understands QM, what is this thing? [forget uncertainty principle etc.]
