FYI, if you are still having issues getting Blogrolling to update your site since the September 28th snafu, and you are using WordPress, you might try turning on the WP Cache plugin. Might just be a coincidence, but ever since I turned it on, I have had no problems with updating.
BTW, from what I have been able to figure out, it isn’t a Blogrolling issue, but one with weblogs.com and blo.gs.
