Online Baby
The Trixie Update is a baby website. But this one is different from all the others I have seen. The style and humor of the author is one reason but the "Trixie Telemetry" is an awesome feature. Basically a little chart that lets you know Trixie's sleeping, eating and ,hum, excreting (?) patterns. A nice bit of coding. They will soon release it as a service as well as the code.
