Tony,
I look at this way.....if a social media makes not a cent for years on end and POSSIBLY never will......where will it be a few years from now?
I then look at it another way...if a social media is not for shopping....why would I have any use for it?
The answers two those two questions are not cut and dry. They are not black and white. The questions are only for weighting.
