I seem to use google reader more and more. Instead of going directly to a site I end up reading the post in GR (google Reader). Some of the major sites I follow
Lifehacker.com
switched.com
digg.com (not so great any more)
techcrunch.com
makeuseof.com
engadget.com
gizmodo.com
blogmaverick.com
It does not seem like I open the sites that much any more. Twitter is the same, I can’t remember the last time I actually opened twitter.com in a browser.
