I think you're response is quite inappropriate. I am not sure how you were able to deduce that the person's skills lack in someway. I don't think there is enough information in the post to make that judgement.

"IT is in boom now"

Are you by any chance living in the 80-90s? :p. Apologies but I beg to differ. My personal opinion is that the field has peaked, which is why you are finding people writing up a webpage and calling themselves a startup. Of course there are exceptions but I am referring to the majority here. There is also large amount of redundant work happening.

IT is and will always be a complimentary field and cannot stand on its own. We are now going through a transitional phase where what was once classified as a white collar job is shifting on the gradient towards blue, so it lies somewhere in between. Maybe Cyan? :).
