I’ve been using Andy Baio’s [upcoming.org](http://www.upcoming.org/) for well over a year now; it’s always been a fairly neat site, hampered only by it’s potential lack of popularity. It’s been good for finding out about upcoming concerts and the like, at the very least.
But Andy luckily got [a kick in the ass](http://weblog.infoworld.com/udell/2005/03/21.html#a1198) from Jon Udell about features that Jon would’ve liked, and Andy has stood and delivered a new version of upcoming that whips all sorts of ass.
What’s new? Well, for one, you can finally add private and self-promotional events; this means I can put *everything* I’m doing on [my profile](http://upcoming.org/user/384/), rather than just the public parties. Also, [tagging](http://upcoming.org/tag/) – just like Flickr and del.icio.us. Plus a developer’s API, a new layout, and email/SMS reminders.
If you’re in a major metropolitan area and not using upcoming.org, you’re doing yourself a huge disservice. Jump on it, folks.
