I drop a comment each time I like a article on a blog or I have something to contribute to the conversation. It is a result of the sincerness communicated in the post I looked at.
And after this article GM Werkzeugmaschinen. I was actually excited enough to create a comment

I do have 2 questions for you if you do not mind. Could it be only me or does it give the impression like a few of the comments come across as if they are written by brain dead people?
:-P And, if you are writing on additional sites, I'd like to follow you. Could you list every one of your public pages like your twitter feed, Facebook page or linkedin profile?
