If you aren't using Google Reader to read this, then stop what you are doing, click the above link, and continue reading this in Google Reader.
Google Reader is the best way to keep up on...everything! It has become my newspaper.
I'm currently using it to track 104 feeds in the following categories:
Almost everything on the web has a feed version that can be read in Google Reader: news, stocks, weather, traffic, blog posts, sports scores, movie reviews, podcasts, etc.
The big time saver is I don't have to go from web site to web site to see what is new...when someone posts something new, it comes to me.
For example, I have all my friends and family blogs listed under "personal." You can see from the above picture that I have 21 new posts to read. Those 21 posts are from a bunch of different people. With Google Reader, you just see the new posts in the same location and can quickly read them all.
It also has some nice keyboard shortcuts so you can do almost everything without touching the mouse. I use the spacebar to advance to the next page all the time.
Another cool feature...you can use Google Reader on your phone, too! Here is the mobile version.
And...the feeds in Google Reader don't have the ads that many web sites have, so it is easier to focus on the content without distraction.
Someone at work recently asked for a recommendation for reading feeds and the response was overwhelming: Google Reader.
I can't recommend this enough: Get Google Reader!
