I've been using Bloglines for several years to manage my RSS feeds. In that time I've seen little in the way of improvements, but a number of notable annoyances (including a corruption of my profile, making me resub to most feeds inorder to fix my last read dates.) Sadly no one else had a web-based solution to compare. Rojo was close, but not quite. [http://www.google.com/reader/view/](Google Reader) when launched had, for me, one of the least usable UIs I've ever used. It wasn't that it didn't work, or wasn't innovative, it was that it presented the articles in a way that was very hard for me to read (a big minus for a product with "reader" in its name.) Yesterday Google released a new version of Reader, and praise be to Jebus, it's actually usable. So much so that I've abandoned Bloglines. All hail the new king.
