I guess no one is an IEEE member 
I dropped my membership many years ago, did not see any benefits in it. IEEE is tribe based, want you to pay for access to anything slightly different from the society you are member of. This was ridiculous.
They were pushing IEEE membership pretty hard when I was in college to the point that they paid for a couple of student memberships for a couple of the chosen ones. I looked at signing up but couldn't get past the idea of having to choose a specific section based on area of interest which really surprised me since I was a college student and didn't know yet which of my areas of interest I was going to end up being employed in, if any. So how do you choose? That was problem one. Then, the other areas of interest being locked off once you choose one, whichever one it happens to be, and join being problem two and between both of them, the disincentive was so strong that I never did join IEEE.
I guess they can't be hurting for members that badly over this since they've never changed how this model of operation works.
I had it in school. Then I dropped it a few years later, around the time of the internet crash, as the relative expense wasn't worth it.
Similar to others, some of my reasons were:
1. Difficult to get information.
2. Every variation needed a different sign-up, etc. I don't know how it works now.
3. Very little corporate or management support or interest.
These days, I occasionally run across an IEEE reference when searching for information. Their database doesn't seem to be indexed into Google, otherwise I would be getting more hits. When I do encounter something, of course it's locked out. Not a problem; other non-IEEE links will usually have what I am looking for.
Membership is $208 with maybe $25 per "society"; and I would be interested in perhaps 6 of them. So that's approaching $400 per year, and to be honest it's probably worth it.
However, I would have to pay it myself. These days corporate long-term views and strategies are so corroded by Agile that there is no way I could get any management support.
