A few years ago, about six months before my 25th high school reunion (my first and LAST attended), I put my info on one of those free listings on Classmates to see who was out there and might be going to the reunion. It was just the beginning of the pestering and nagging by Classmates.
It is, at the very least, an interesting study of a business model: you pay for any single thing you want to do on Classmates. That's it.
At first it was exciting: "A friend from high school has visited your profile!" And when I went to the website, I found... I had to pay and get a "gold" membership to see who that person was. For the past 10 years, they periodically tease me with "someone from Classmates sent you email!" or "six new members of your high school class have signed up," and the most recent was "this member of your class [greyed-out photo] wants to hear from you--do you know who this is?" Of course, if I click on it, I get the screen that says "join and pay for a gold membership to see who this is."
There's a handy option called "delete." With a few choice words, I have another name for that button.
As soon as I finish this post, I shall attempt to de-list myself from Classmates, if such a thing can be done. It only took several dozen attempts and three years to get my resume and profile off of monster.com.
