I do like to read blogs which I found to be interesting. The old ways is to open the blog directly but that is such a waste of time. There might not be updates and you might be reading again old posts.
So the best way to me is to use Google Reader which keep tracks of the blogs that you register with it. That way, you just read new updates of the blogs.
And for iPhone, you have the benefit of using the app called Reeder to open google reader in such a simple way. I just open it and it would start downloading updates of the blogs that I follow. It’s easy.
