When I share my PowPing post (that has only text, no image) to a Facebook Page, it seems to use my PowPing user profile picture as the Facebook default image.
Basically, Facebook blows my profile picture up to an enormous size and considers it the default image.
Not ideal. In the very least I would prefer not to use my picture like that. However, it is perhaps a missed opportunity to market PowPing is a more viral way.
