Generally that's a great idea and congrats to Wimpie for coming up with it. New players is what BM needs the most and getting social and tapping those hidden potential playerbases is the best way to get them.
Some ideas of where to look for new players:
- reddit
- indie game message boards (eg. bay12)
- discord
- tabletop communities message boards, local even
And don't forget to use many hashtags on twitter (I'm probably stating the obvious here).
