Reader..

I have been using Google Reader as my RSS Aggregator since it came out as a beta product from Google Labs.
Google have updated the UI of the Reader into a New design today, which looks cool and almost the same as the ones which can be installed on a Desktop.
Google Reader is really nice tool, which helps you to Subscribe for various Feeds and receive them as and when they are updated. For example, I subscribe to Orablogs Feed, which gives me various articles written by some Oracle Techgurus and help me to be updated on the Oracle techfront. Another is the Planet Kannada Feed, using which I can read through all the Online Articles published in many kannada blogs.

One can even Subscribe to News Feeds and get updated news as and when they happen.
