A new version of Blam has been available: 1.8.7 (latest release) http://www.cmartin.tk/blam.html The 1.8.5 cannot be installed anymore because of a conflict with new libraries.
Blam is updated in F-13, it isn't yet updated in F-12, because it would not render the posts correctly. There is an update sitting in updates-testing you can test: https://admin.fedoraproject.org/updates/blam-1.8.7-2.fc12 To install try: yum --enablerepo=updates-testing install blam
This is actually fixed now, blam updated to 1.8.7 in both F-12 and F-13.
