Facebook Explosion

Picture of the Day for 1/20/2015. My company's Facebook page has been going wild. We've gained about 25 new "likes" in the matter of a few days. This is unprecedented. My sister Robynne and I have been trying to figure out where in the world all these sudden likes came from (Pinterest? A post we made on one of several speech therapy pages on Facebook?) but we can't determine the source. Not looking a gift horse in the mouth, but we are curious.
