One of the very best things about Facebook is that it reminds me when people I know have a birthday (assuming they have chosen to list it on the site). On the flip side, I received over 50 messages on my birthday from folks all over the world--pretty cool, I must say! (Also got a few phone calls, IMs, text messages, and such, too.)
When I was a kid, it sucked having a summer birthday, as you missed out on the chance to celebrate in school. Technology has made it a lot easier to touch base on birthdays.
