Very true - there are also the Youtube network companies and other external parties, who also promote the channels they have under their wings (for a revenue cut) using various "rent-a-mob" techniques and some who try to disguise what are in essence "infomercials".

Personally I'm not really motivated by the financial side (nor need to be), but I do enjoy doing the videos for their own sake and more to show people that they can also do great things using CNC. It also helps answer a repeat question I get i.e. "what on earth are you going to make with a CNC machine" when I tell them I've built one myself - maybe I should do a channel intro vid along those lines.
