I think that could make sense in the long term, but with YC companies on demo day, I'm not sure it does. Most of these companies appear to have <1000 followers on the services you're measuring. If Likes and Followers cost a dollar each, then it wouldn't be too expensive to buy a spot at the top of your list in this case.

It's interesting that the company at the bottom of your list (Reebee) has 3x the Twitter followers and 6x the FB followers that the company at the top of the list (OneMonthRails) has. If Reebee started out (i.e., when you started tracking them) with a couple hundred followers on each of these services and OneMonthRails started out with none, then Reebee had the deck stacked against them, needing to add 100x+ the number of followers added by companies that began with no traction, during a limited time frame.
