read the manifesto and you'll see why: http://feathe.rs/manifesto , its all about the writing experience. and in about being able to have posts not linked among them as normal blogs do by listing them. Its more ment for the social web, that's why we called feathers as each post for us is like a feather traveling on the web via social sharing... think of it like the iAwriter for the web :) Of course tumblr still rocks and for its purpose is ok, we just wanted somethign faster, simpler, more minimal..read the manifesto there you'll find why we hacked this project together.
