Update:Finally, I create myself a Feed Reader: http://azreader.net , everyone else can also register and use it.
I believe READ is a must for a reasonable person.
After google closed google reader,I was trying many similar tools to manage my rss links, however, all not easy to use. Finally, I tried outlook, not easy to use too. I can't tell how, but outlook wasn't designed as a rss reader.
In my mind, a good rss reader should have the following features:
1. Keep my rss content online, so that I can read it any where, any time.
2. I can search content.
3. Fast and stably.
So far, I found two tools are usable. One is bloglines
One is http://digg.com digg reader.
Digg is slighter better, and I am happy with it now J
