I've recently put together a web-application and am looking for beta testers. Instead of doing the super-private sign-up here and we'll maybe let you in beta testing, I'm doing the "you came across/read this blog so may be interested in trying out a cool app" signup.
Think Calendar and Traveling.
If you're interested, and actively use (or will start using) GoogleCalendar, or an iCal program like Appl iCal, Sunbird, AOL Calendar, et al. then drop me an email at: firstname.lastname@example.org and I'll let you in on the info.
The idea is I want to test with a small number of "cutting edge" users before releasing it public. It's easier to fix bugs and answer support requests that way. :)
