I’ve been testing NewsAlloy, a free, feature rich and very fast Ajax reader (zero page refreshes). All power-user features are included – tagging, pinning, river of news and folder-based viewing, easy digg and del.icio.us submission, and good search capabilities. I also like the keyboard shortcuts.

If the speed holds during user ramp up (a big if as the site has only been up since around December 1, 2005), this could become a cult favorite. However, this is not for RSS newbies.

Pete Cashmore wrote about them right after launch in December.
