LJ sacked about 25% of the San Francisco office staff. Not the 30-60% (and higher) that's been floating around in the rumorsphere. What's particularly ironic is that this was being reported by Gawker Media's ValleyWag, the victim of huge layoffs (60%, well, 3 of 5 people) back in October.
Gawker has since revised down their original numbers (20 of 28 staffers fired!) after Livejournal, Inc. released a statement to cnet.
