In case you missed it, Pownce announced the release of the second revision of its public API today. The new API is much more elaborate than the previous version (which was honestly kind of a joke), and promises to be robust enough that interested parties could use it to rewrite the Pownce desktop app from scratch without losing any functionality. This will really encourage a lot of third-party apps to be developed for Pownce, and will probably be the thing to get the adoption of the service to really take off. I hope they have a nice caching solution for the API, because I suspect a lot of folks will be hitting it up soon.
You can find the API documentation here. I haven’t had a chance to give it a thorough review, but my first approximation is that it is just dripping with awesome-sauce. If prompted, I might even go so far as to say, “w00t!” :-D
Hack away, folks!
