Here’s a troubling signpost about the state of Digg–Kevin Rose is apparently not all that into the service anymore. The site’s founder didn’t submit a single story for a stretch of 22 days at the end of last year, and is currently averaging around one submission every four days. Rose submitted seven stories in 30 days–versus 181 tweets. Or, as TechCrunch puts it, “He’s 26x more active on Twitter than the company he founded.”Is Rose over Digg, or is he just taking a bit of a break? Things are a little better for current CEO Matt Williams, who is submitting a story a day on average. Better, but not great.Of course, all of this comes in the wake of a redesign last summer that caused a massive backlash against the service. Digg insists that all is peachy on the site, and so of the disgruntled users do appear to have returned, but things are definitely down overall..
