Upcoming.org gets an API

Waxy sez, "Upcoming.org, the social
calendaring site I created in my spare time, now offers a ton
of spanking new features. Among the big changes: a complete
API for doing your own development, and support for tagging,
e-mail/SMS reminders, and personal events. Why the sudden
flood of activity? Blame Jon Udell, who posted this
column
inspiring me to do a week of nonstop coding."
