I actually do have 2 questions for you if you don't mind. Is it just me or does it seem like some of the remarks appear like they are coming from brain dead folks? :-P And, if you are writing at other online social sites, I would like to follow everything fresh you have to post.
Would you list the complete urls of all your shared pages like your linkedin profile, Facebook page or twitter feed?
