Clarke on Snow Leopard
I forgot to mention that Clarke now works on Snow Leopard, using that Core Location cleverness. Which might make it the first app in the wild to do so, although I'm sure someone will tell me it's not.
People have asked me to add support for Google Latitude, mapme.at, or Brightkite and all those things. I don't use them, but the source code is on Github, and I'm happy to merge changes back in. If you want to update your Twitter location automatically, EagleTweet will do the trick.
The only thing I still want to add is the ability to ping a URL of your choice when your location changes. For those home/office automation tricks.
And yes, I know the menu icon is still in colour. It's on Ben's voluminous todo list.
