I'm curious: Who uses a calendaring program?

[Acco]

How many of you guys use a calendar app (Either on your desktop (Sunbird, iCal, Windows Calendar), mobile (iPhone Calendar App, Android Calendar App), or web based (Google Calendars, Windows Live Calendar))?

I'm thinking of updating a calendar that you can subscribe via CalDAV, Exchange ActiveSync, .ical import, etc. Just because the calendar system in use currently doesn't support it. And honestly, I think it's a pile of junk unless you can view it on any calendar program you choose. :) I've already got such a system up for my own personal use... keeping my phone and desktop calendars in sync, but... if I were to publish the calendar, would you guys use it?

It wouldn't decrease the amount of sites that some people would have to view or applications that people have open, but... for those that do, it'd make this convergence thing a lot easier.

Edit: You can still also get the weekly digest through http://www.twitter.com/vfur though. This is for local events only, though.

That's an awesome idea.  I'd definately go for that.
