“Tumblr’s contextual bookmarklet has changed the way I use the web. It’s partly why I now recommend Tumblr to anyone who doesn’t want the burden of a “real blog,” but who’s also interested in giving the internet something more substantial than a one-hundred-character complaint about their meal and the person who served it — people who have that itch to share lovely bits of the world that come over their transom throughout the day without stopping the other things they’re working on.”
