What if this is an app for women to find a relatively well off (replace with intelligent, etc) partner given that this app is, essentially, a filter that dictates level of income/job bracket (location dependent, but you get the idea).
And if you're a hetero woman dev, chances are your network is already filled with hordes of eligible bachelors a degree or two away -- if you even want to date in that pool.
I think that's the biggest "if" here... "devs" are not really a sexy stereotype in the way that date-an-athlete or date-a-doctor or date-a-rapper would be, I don't think. If anything, it probably hurts your chances. I certainly wouldn't go around throwing, "Hey babe, ever been with a dev?" Lol.
