Flickr’s co-founders Stewart Butterfield and Caterina Fake (husband/wife team) recently resigned from Yahoo!. Stewart wrote an incredible resignation letter.

Of course, Valleywag calls it “bizarre”, “rambling” and “entertaining nonsense”, and a majority of the comments are no more flattering. I (and some of the comments) get it, though. It’s rather brilliant. Stewart reveals himself to be a well-rounded, liberally-educated guy who can actually write! Of course, I could feel that in all of the presentations I’ve seen from the Flickr founders who always come across as having a real grasp on the human nature intrinsic to a social website. I think we (designers of interactive content, whether it be the web or games) could learn a huge amount from Flickr and the views of its creators.

In fact, I wrote about this not too long ago (from the UI designer at Flickr). Read the essay. Get inspired to create something for people.
