Thomas Hawk reports on a preview of 83 Degree's latest project, 30 Boxes. It's a calendar with built-in social networking. It should be available on Sunday. Check the 30Beta Blog for details.
Alternatives include AirSet and SpongeCell and HipCal, according to comments to the post, and of course there's the age-old Yahoo Calendar (which means there must also be a Google Calendar on the way).
Indeed, with the Ajaxing versions of Yahoo and Microsoft Live apps now in beta, the window of opportunity for these sites must be very small. If you already have mail, contacts, bookmarks, notes, a blog and a messenger service that work with your calendar, why would you go to an external site?
And if you already use Microsoft Outlook's functionality -- eg, drop an email on the calendar to create an appointment -- and it automatically syncs with your PDA and/or phone, then an online service that doesn't sync is completely worthless.
