They actually care about their alumni more than most universities care about theirs. The university I went to pretty much pretended I didn't exist, except for the once-a-year mandatory letter that said "Give us $100 to maintain your status in our alumni network." The benefits I'd get were basically socializing with other alumni, which I had no interest in doing.

If you graduated already, and therefore stopped paying tuition, it doesn't make sense for you to expect any additional services. I'm really grateful that, even a year past graduation, they still review my resumes and other professional documents. I haven't paid them a penny since I've graduated.
