Another list of KM sites

Lucas McDonnell provides 31 essential knowledge management sites, which may end up growing beyond 31.  (The URL suggests it was originally 26.)   Most of these sites are blogs with a few other types of website that are frequently updated.

Sadly, a few of the sites listed aren't nearly as useful as they once were, either because they haven't been kept up-to-date or because their audience moved to other things.

Oh, and I am in the list.  Thanks, Lucas!
