1. Tweet - Yep, with the help of your Twitter account, now you can "share" interesting feeds with your friends more easily.
2. Read it Later - Say that you've found something interesting but simply don't have the time to read it now, then you can use the new "Read it Later" feature which automatically bookmarks the Feed which you can use to read them later.
So if you use Ubuntu 10.04, 10.10 or 11.04 you can easily install Read-Me using a PPA channel. Open your Terminal and issue the below command.
sudo apt-add-repository ppa:atareao/atareao
sudo apt-get update
sudo apt-get install read-me
