I had tried out Google reader during the days it was first launched. But I was much comfortable with sharp reader those days and didn't wanted to move. As time moved on and I changed machines and firewalls, I some how stopped using a feed reader and started to just browse to the blogs.
I saw few posts on how well the Google reader has evolved from Merill and few others over the past few months. So I setup the Google reader today with the blogs I read now regularly and it seems quite good, perhaps even better than a windows application. I think I might stick to it at least for some time.
