Getting people with social capital on board is absolutely worth it. In this case we may have overestimated someone's social capital (she made posts about SteemIt on Facebook and Twitter which got a few likes, while her selfie shortly after was shared by thousands), but it's not a big deal in the grand scheme of things. I do hope she keeps posting here. Her really big first two payouts may have set expectations too high, and the third one was essentially "give me money to give to my friends" which flopped.
I don't particularly care if her boyfriend is handling her account. She is clearly involved, as you see from her videos.
