En route to academia, are professional society memberships useful? So far, I feel like I have been paying ~$100/year for a few societies (with student discounts), just to receive copies of their monthly magazines that I only end up skimming over once. I get tons of emails that are vaguely aimed towards keeping people up to date with current research, but one can do that by reading papers anyways. So I don't really see a point to being a member.

Does anybody else feel this way? Are there actual benefits to being a member for societies like these?
