3. Required registration? Get real.
When I tried Classmates.com I couldn’t even look at my high school class list (or any other class) without first giving my personal information, including e-mail address. See a connection here?
4. The service itself strikes me as antiquated and useless.
I can see how Classmates.com might have been appealing back in 1995, when it first launched. But nowadays, you can find better and easier ways to connect with old classmates -- ones that are both cost- and spam-free. (Facebook, anyone? MySpace?) The company's audacity in continuing to lure curious people into paying money to find out what "mysterious person" is interested in them just floors me.
5. What kind of pay-to-play company doesn't make their phone number readily available?
