I just submitted LOLCats 1.2, which will most likely be the last version. The major new feature is Zooomr support.
I’ve shifted my attention to the Official I Can Has Cheezburger app, which will use RSS feeds from that site & related sites. Most likely I will pull this application when I release the official one.
I’m also working on a more advanced Flickr browser (LOLCats was a proof of concept for it).
