Today Gothamist launched their events calendar. It seems to be similar to mine in scope, but with less of a focus on music (also, their's is stocked with events by "professionals"). The biggest difference is they are using upcoming.org in conjunction with Movable Type to manage the page, while I am just using MT.

When I first created my events page there was no such thing as upcoming.org, so I didn't use it. When it was launched I was a little bitter because I had a similar idea at one point and never implemented it. Now, after seeing Gothamist's page and reading Kottke's talk on cooperative web services, I think I will also move my events to upcoming.org. It is good for everyone.

In the meantime you can check out the stuff I do have up on my calendar and see what Gothamist has to offer. If you want to do this yourself, follow Matt's instructions.

Also, if you would like to contribute to my calendar is some way, you are more than welcome. Just shoot me an email (available in the sidebar).
