I want to point your attention to a short but valuable post on “Owning vs. renting” by the thinker Seth Godin. Seth has a way of feeding new dimensions into obvious topic. I read in “Be good” and “Keep learning” into this message. You cant and should take advantage in an unfair manner of the position you or your product have since you will find your “rented position” cancelled by your customers, users or competition if you do not behave correctly or if time leave you behind.
