Before I have read the news feeds I am interested in via the Firefox plugin “brief”. It did all I wanted it to do, but I had all the data and metadata (all the feeds and read items) only in one browser. I was not able to have a shared state at work and at home.
Now I installed rnews on my webserver. It is multi-user capable, so that multiple people can read the feeds they are interested in, without the need to have multiple installations. I can use it from any place where I have an internet connection, without losing the state.
