I'm still looking for the perfect news aggregator. Today, I downloaded a very impressive Java application, dynamicobjects spaces. I was reluctant to do so, because I have not really seen many Java desktop apps that I like. But this one really looks great.
Unfortunately, it doesn't work for me - I can't get the RSS subscriptions to work. I have emailed the author and look forward to his reply. Meanwhile, I'll take a look at other options.
There must be plenty of RSS readers that would deliver what you needed.
I use Sage which is a RSS and Atom lightweight news aggregator which is a Firefox plugin. It’s mediocre, but there is nothing fancy about a news feed to begin with, so it gets the job done.
What kind of fancy do-dads were you looking for in a news reader?
