Is does not seem to offer something for me, which will make me switch. In fact I miss the API. It is time these kind of services will accept bookmarks in a feed-format. I do not want to submit my bookmarks to all those site. Well, I imported my delicious bookmarks into the service (at least I think, they have not yet turned up). The interface is nice, but uses to much space for one bookmark. And the bookmark thumbnail is plainly wrong. I like the short link: a permalink for a bookmark! Is the rating useful? I am not sure about the social thing. There are already to many of those and I surely get my daily info-shot already.
