I’m a big believer in Norvig’s “Code is liability” maxim. Which is how I justify my ugly, but functional Flickr API implementation, in 40 lines of PHP (not the most expressive of languages), which I wrote in about 15 minutes one evening, and I now use for all of my Flickr side projects. And all apropos of digging through other folks Flickr API impls, trying to get them working on GAE. Thankfully blech is already there.
