Hurrah, it looks like Bloglines have finally resolved their 301 handling. Also they've announced a Publisher Tools programme to help Bloglines to work better with your blog. It still needs the "publisher" to be a Bloglines user, but it's certainly a start.
Now what about some of their other problems?
Update: The "claim my feed" process is a complete pain in the arse, and I've not managed to get it to work yet despite the required codes appearing in both my feeds and htm. This is not the sort of freedback that Bloglines were after, but I guess it's best they know.
