Bloglines has fixed the glitch that was causing Workbench's Atom 1.0 feed to display incorrectly, as a feed preview demonstrates.
I reported the bug to them in e-mail last week and was told they forwarded it to the "appropriate technical department." I never figured out any possible cause of the error, but the fix is another sign that Bloglines is a lot more actively maintained today than it was a year ago.
I threw up a new entry, and my posts are no longer signed bytehead at the end. :) I was just a little surprised that Bloglines decided to show all my past posts, but I think that's due to the change that they did.
