Digg - 420 diggs as of this writing. Not bad, but not stellar. Reaction ranges from congratulatory to disappointment and getting interviewed but not quoted.
Reddit - 82 points. Much investigation into the identify of Reddit user "Adam Fuhrer," a supposed 12-year-old from Toronto. More here.
StumbleUpon - 435 stumbles. Little comment.
No sign of the WSJ article getting much bookmark love. 287 bookmarks actually.
Newsvine - 31 votes. Discussion is all citizen-journalish, of course.
Netscape - 95 votes. Commentary somehow devolves into a strange internecine squabble. Jason Calacanis present, though uninvolved in squabble.
