I was surfing the net this weekend, when I came upon this post at The Unapologetic Mexican about the founder of the DailyKos blog - Markos Moulitsas. It seems as if there are serious questions as to the background of Mr. Moulitsas, and how said background can cast doubts about the very intentions of his blog.
Francis Holland has also done a gathering of 'evidence' in this issue-The Indictment of Markos Alberto Moulitsas ZÚÑIGA by Justice and History
At My Left Wing, there is a gathering of links on this subject: Blog Roll on Moulitsas Conflicts
If nothing else, it will very interesting reading.
