I create a comment each time I appreciate a post on a site or if I have something to valuable to contribute to the conversation. Usually it is caused by the passion displayed in the post I looked at.
And on this article Chihuahua von den 7 Zwergen. I was actually moved enough to leave a comment

I do have a few questions for you if you do not mind. Could it be just me or do some of the remarks appear as if they are written by brain dead people?
:-P And, if you are posting at other sites, I would like to keep up with you. Could you list every one of your public pages like your twitter feed, Facebook page or linkedin profile?
