I've moved over to Polywork. Which has a bit more of a tongue in cheek feel, but definitely feels better thank Linked in does, with a better community.
They get mentioned in a random HN comment, they'd potentially get a few hundred new members but it's impossible to sign up so everyone moves on and in a few minutes will forget that site even exists.
