Yesterday I had just bumped into Liferea(Linux Feed Reader). A free RSS, ATOM, etc feed reader for linux users. I was impressed with its ability to show feeds like I reading good email without junk. It is also capable of searching feeds from Feedster and showing it to you, all from within Liferea. Smart isn't it?
And just after an apt-get today I found new official packages for mozilla-thunderbird 0.8 were available for my Debian box. Thunderbird also has a nice interface for a feed reader. It can be made much more powerful by adding the Feedster search feature of Liferea.
The only feature I was expecting theses feed readers would have is to show comments too. Wouldn't that make the blogs like really "tiny" newgroups. Hope the people using newgroups do not stop using them with all this blogging thing happenning now.
