HM alone does not, but one of Digg's problems is that they are facing a pack of ravenous midgets that focus on one specific niche. If you are interested in a small selection of niches then Digg is simply a useless place to go for information -- what you care about will never surface and all you see is a bunch of articles trying to game what remains of the general interest audience Digg once commanded. You could walk down a list of all of the major Digg categories and list two or three sites that do the job better for that specific niche; this is what is going to kill Digg. Digg is like an online social newspaper, and it is suffering the same fate that the print versions have gone through with better competitors peeling off profitable niches and leaving a dull husk behind.
