Marianne just totally cockblocked me by mentioning that incident! It was a single isolated incident, mind you. Someone I've been talking to on OKCupid reads HN and found this post, which has now led to a heated argument about whether I'm a human capable of love or a Siri-like chat bot optimized for professional networking.
I'm not sure about that, it seems very regressive to me, playing into the stereotype that the way for a woman to succeed is by attaching herself to a successful man. I would say it's one step away from flirting with your boss to get a raise.
I'm not sure if Tal had underlying motives behind her OKCupid use, but I don't see any problems with someone (regardless of sex) going on a date, and going, "Hey, you work at [company]? Do you know [person]? Mind if you introduce me to him/her?"
Especially if the person's also in the startup scene. The ecosystem thrives on people helping each other out.
I fully agree with you that that's perfectly acceptable behaviour (if you didn't know in advance that they knew [person], or else it gets a little unethical...)
But from the phrasing of the OP ("great hustling"), I took it to mean that she was actively "hustling" OKCupid by using her dating profile (i.e. people's desire to sleep with her) to get business contacts (i.e. money).
