Reddit : Digg == Slashdot : Kuro5hin
I unsubscribed from Digg quite a while ago, not on account of any shenanigans that I perceived, but because a) it had too many stories, with a very low signal/noise ratio -- at least for me b) the stories seemed to be slanted more towards sensationalism and somehow getting a visitor to have a look at them and c) quite a few of the submissions were really old ones, reminding one of the Eternal September.
