RSS readers

I am looking for a feed viewer for windows. What rss viewer are you using?

I use the one that is embedded with Thunderbird, but it has many problems and it is not so good.

Can you please recommend me a better one? Thanks in advance :)

I use the google feed viewer
or the one from firefox (for urls)

Second Google reader, though you do obviously need to be online to use it, I find it by far the best reader I have used, though like Olaf I use firefox bookmarks for RSS feeds of URL lists like Dzone, Digg etc

funny I used thunderbird a while but didn't like it...

Yeah that was the motivation to post this thread :)
