If you actually want to make out flirtation is usually the way to go.
I guess it depends on what your long-term goals are.
Hooking up within seconds of noticing each other is not that uncommon in certain venues, and I haven't noticed any downsides to that.¹ (My inner Umesh says this just means I don't do that often enough, and I guess he does have a point, though I don't know whether it's relevant.) Granted, that's unlikely to result in a relationship, but that's not what drethelin is seeking anyway.
r/Fitness does a weekly "Moronic Monday", a judgment-free thread where people can ask questions that they would ordinarily feel embarrassed for not knowing the answer to. I thought this seemed like a useful thing to have here - after all, the concepts discussed on LessWrong are probably at least a little harder to grasp than those of weightlifting. Plus, I have a few stupid questions of my own, so it doesn't seem unreasonable that other people might as well.
