10. You Have Unrealistic Expectations
What online dating is: A chance to meet a bunch of people with like interests, and possibly start dating some of them. What it is not: A magic love potion that will match you with the woman or man of your dreams, followed closely thereafter by a fairytale marriage or whatever it is your heart desires. Online dating is a forum in which people are matched, and sometimes it works really well. Sometimes it doesn't. The point is to keep an open mind and a sense of humor. It may not be for everyone, but I think it's worth giving it a try.
