I notice all advice on finding a girlfriend glosses over the actual nuts-and-bolts of it. In Alicorn's post here, the assumption seems to be that there's an immense pool of women receptive enough to me (e.g. by common acquaintances, organizations, etc.) and I can just roll the dice until I find one, and all the supposed problems for rationalists worth getting advice on, arise ... er, sometime later.

Where am I supposed to find this pool of bachelorettes? And if it's common interest organizations, which should it be, since we've ruled out those related to rationality? And isn't it strongly advised not to show romantic interest soon upon joining such an organization? In which case, how does your advice differ from "Join a random group ... and wait ... and wait ... and wait"?

FWIW I recently joined a group (actually a subgroup of a larger group which is not held in high regard here) and did click with one of the women there, and asked her out, but we only went out for a few days before she lost interest. And then I found out there's a taboo against dating within the subgroup (though I don't think that had anything to do with her calling it off), which puts me right back to square one in terms of being expected to start relationships with near-complete strangers.

With apologies, it gets a bit annoying constantly getting dating advice that assumes away the most critical problems, and I can't be the only one in this position.
