New Google Product: Google Romance
Exploring the nooks and crannies is fun, especially this page with links to a history of other Google Products released on this date in history.
It's a shame though, as I was hoping they'd pull a Gmail and finally release the Google Calendar, aka CL2.
UPDATE: Didn't notice before, but Gmail has a special birthday logo today after you log in. It's the little things that make me so happy.
