Hope your blog post didn't just make the front page of Digg.com! The site is offline — in the middle of the day no less — while "changes" are made. We've got no idea what the changes might be, but unexplained downtimes in the middle of a business day suggests an unplanned outage. Got the scoop? Shoot us an email at firstname.lastname@example.org.
UPDATE, 10:42 A.M.: Digg has returned with no significant changes. The 'share' button still doesn't work on Macs in Safari or Firefox either.
