Update (4/5/07): Check out www.missingmethod.com for a better idea of what I’m up to these days.
My Projects:

• Curbly – a DIY design community for people who love where they live.
• Feedmarker - a free, open-source bookmarker and newsreader with tagging.
• Snapballot – dead simple surveys
• Teacher! – a lightning-quick online gradebook for teachers who hate busywork.
• Acu.mn - all your local news in one place
• Walker! - create, tag and share Google maps. Plot your favorite neighborhood walk, or the way you drive to work, or the best places to visit in your town (offline)
• Notetagger – social notetaking and outlining for lawyers.

If you’re a web developer, there’s no reason why you shouldn’t be checking out Ruby on Rails.
