Why is it stupid? Has anybody - yet - clearly become the RSS reader? Is there any reason to think that the Digg guys might not have some innovative ideas they could potentially deploy? Will their brand recognition alone not give them something of a "leg up" (even after a couple of years of irrelevance, people still remember the term "Digg").

Don't get me wrong, I'm not saying they will succeed at this, but I don't see the justification for calling the move "very stupid".
