Apparently Google doesn't think Digg is worth much more than a few kilos of panda poop tea these days. Digg.com is currently MIA in Google's index.
While we've yet to hear comment on the matter from either Google or Digg, it looks like Digg has been penalized for something or other. Either that or Google made a huge mistake.
If you just search for "digg," digg.com is nowhere to be found. Instead, you'll be treated to the Digg WIkipedia entry, the Digg Twitter account, and various other pieces of content about Digg.
Some are already wondering if Digg was busted for paid links or other some other kind of link scheme kind of thing. I'm sure we'll find out soon enough, and we'll update as we learn more about what's really going on.
Digg, as you may know, recently said that it's working on an alternative to Google Reader.
Update: TechCrunch managed to get a statement from Google, saying, "We’re sorry about the inconvenience this morning to people trying to search for Digg. In the process of removing a spammy link on Digg.com, we inadvertently applied the webspam action to the whole site. We’re correcting this, and the fix should be deployed shortly."
So yeah, Google made a huge mistake.
