If that were the case then I would see no reason for an R/S but I don't invest based on "Likes", no way, no how will I do that. I can go to just about any product FB page and see all the "Likes", that doesn't always translate to sells.
I'm merely looking at worse case scenario here but I see where you're going. One can only hope that 10% of these "Likes" translate into sales. A dream come true for sure.
