I don't get any commission or perks, but I would honestly still encourage you to join the IEEE: It takes its mission of "foster[ing] technological innovation and excellence for the benefit of humanity" quite seriously, plus you get a copy of IEEE Spectrum every month, filled with cool articles from me and my colleagues -- if there's a deliberately moving electron associated with a topic somewhere, we're likely to cover it. :)
OT: I keep meaning to join IEEE - do you get any commission or perks for referrals?
