After a while of development we can now say that News Stacker is in a public beta environment. As this project will rely more on performance than on the code behind it we decided not to only test internally.
With News Stacker you can read your RSS feeds in a more managed way. After a short registration to create your own personal stacks you are able to create channels. Each channel represents a collection of one or more RSS feeds which we will call stacks. After registration you will also be granted with a personalized News Stacker pages which has a main stack (containing all RSS feed items) and subpages which present your own channels.
So please stop reading and start stacking at http://www.newsstacker.com
