LinkedIn - Using it wrong?

I'm not sure what is 'required' vs LinkedIn trying to make $ off of me... but the constant reminders to post, self-promote, add people to my network... it's all so... stupid.

Am I doing it wrong? Can someone please explain to me how all this crap helps? Is just putting up my experience + resume and adding people I actually know and respect enough?

Venting a bit. Sorry.
