Online dating takes a somewhat different mindset than IRL dating, dewd. IMHO the way to do it is send the same copy-paste hello to every girl/boy/Jewish furry Scientologist (depending on your preferences) you think you might be interested in, then see how many reply to you and how many you can actually maintain a conversation with. The ones who don't or barely engage you ignore because you've got half a dozen others in the wings. You cast a wide net and gradually narrow it down. IRL people would think you're a slut or player for doing this, but the whole advantage of online dating is that you can do that shit and people don't really care about a few text messages and you don't have to go to the expense of buying someone dinner before figuring out if they're a dud or not.
