Bloglines, my preferred RSS reader, is showing new vigor. They've added the ability for feed owners to manage how Bloglines manages the feed: Bloglines | Change Profile.
They've also added a way to provide feedback to them from a blog, which I'll use to tell them that the 'Change Profile' tool didn't recognize any of my Blogspot blogs -- and I read them all via Bloglines.
The trick for the feedbak is that I include the phrase bloglines freedbacking in this post. Their search engine looks for this and flags the post as feedback.
