Online dating is pretty much the easiest, lowest-rejection form of dating there is. You basically shop for a date, and the only difference is that sometimes the date you want to buy says no. Okay, that metaphor took a kind of wrong turn, but what I'm trying to say is that worst case scenario, someone doesn't reply to your message or actually says no (very rare).
I realize that a person saying no or not responding is technically rejection, but it is rejection in the form of messages sent back and forth through a third-party dating site. It's so low-commitment that they don't even have your real email address or phone number to reject you by, and unless you have a really overactive imagination, you aren't all that attached to the person anyways, right? It's not like they looked you up and down and laughed in your face, or like you are now left standing next to them on this really awkward 30 minute bus ride, or like you've just ruined the only real friendship you've ever had by trying to kiss them. It's via the internet. This rejection doesn't even count. Especially when there are so many factors involved, because we all know people are way pickier about details like religion, industry of work, education, favourite bands, hobbies, car ownership, etc., when it's all laid out for them online. They don't really know you, you don't really know them.
All this to say, these sites have taken the least-put-yourself-out-there form of dating and made it even easier with all the other features: you can make someone your favourite, click that you want to meet them, give them a star rating, or whatever else that will end up as a little notification in their inbox that you're interested without you even having to take 2 minutes to think of an opening line for an email. DON'T DO THOSE THINGS. They are lame cop-outs. You have now either put all the onus on the other person to make a move, showing your cowardice (not sexy) or are playing this thing like a numbers game (not sexy). If you're interested, just send the person a freaking message already.
Which brings me to point number two: after sending a couple of messages back and forth, I am of the belief that you will not learn anything more of use until you meet up. A couple of messages have probably established a few mutual interests and the fact that once you've found them out you're still intrigued by this individual. This isn't a place for pen pals, no need to keep writing each other letters online, at this point you need to know if you have any chemistry and the ONLY way you can do that is by meeting in person.
Got it? Send the person a message. Ask to meet up as soon as you've established a few basics. If they say no or don't respond at that point, move on. SO EASY!
Remember: everyone who's on here is at least copping out a little bit. We want to meet new people with a safe online buffer. The buffer is there so that you can do the ask-out-on-a-date-thing without heart palpitations. So just bloody well ask someone out on a date.
Thank you and good night.
