If you have not visited the Cliopatra blogroll yet, it's a knockout with plenty of (non-ACW) history blog links.
I'm sorry to see the Carnival of Bad History seems to be having trouble organizing its sideshows. In the meantime, we'll soldier on with our own carnival of bad Civil War history right here.
Cliopatra, the group blog, is also worth a visit: its link to the Apocalyptic Historian (and her recollections of Shelby Foote) is especially rewarding.
