Since Nir didn't bother telling me what Pinterest actually <i>does</i>, I checked for myself, and it appears to be... a Tumblr clone.<p>A Tumblr clone with $27 million, and a bunch of users, but so what? What are they actually doing any different from Tumblr?
I think that companies like Pinterest don't need lone wolf type of developers, but should look to buy whole shops of quality developers who are currently in the wrong business, but have the brain to architecture and scale.
