>The average woman on dating sites gets hundreds of messages, and the average guy gets tens. That is a MASSIVE imbalance in favor of women.
Not sure that's necessarily a massive imbalance. It depends on the quality of the guy sending you those messages, and maybe on the actual message that they send (but it's more important that the guy is hot than that what he says is funny or something).
For example, I get a ton of emails from spammers about penis enlargement methods, and I rarely send my own emails asking if they have any penis enlargement methods available. Does that mean there's a massive imbalance in favor of me? It's not like I'm at a huge advantage because of all this email I'm getting.
