I, as a blogger, enjoy when people appreciate what I write (obviously), and comment about it, and may be follow me, but only if it is out of a total freedom, hopefully if it's really meant it.
I, personally don't follow blogs only because I want that they follow me, I read blogs that I really enjoy or that I find interesting.
And when I comment, I mean it, it is not because I have to.
It is true, that if you want to be known, and if you want to raise your readers, you have to visit and comment on other blogs, or join communities, as I did, however I want to stay true to myself, so I follow and comment only on blogs that I really like.
Thanks for listening.
