If you are like most people, that is, either within the category of "average" or "below average", I'd say the indifference in which you'll be treated is not worth it. Not worth the pain. The system is rigged in a way that everyone believes they can get an "above average" person, just as easily as putting money into a vending machine and getting something back. Anything less than what you wanted is rejected. I don't know what has caused society to become like this, but it's pervasive, and sickening. (As a disclaimer: I don't mean the individuals in this thread are guilty of this, I'm speaking in general.)
On the other hand if you are thick-skinned, you might be able to endure months of getting no unsolicited responses and few replies, and hoping you can find something that will suit your purpose, whether it be short-term or longterm. I lack the iron constitution, so online-dating is not for me. It would have be to learned masochism, if I was going to persevere.
