Online Relationships: Good or bad?

I never used to be a big fan of online relationships. But recently I have changed my mind. Not because I have actually had an online relationship or anything, but because the advantages outweigh the disadvantages. And because I watched You've Got Mail for the first time. First of all, you can remain anonymous, so if someone starts to get weird or too pushy, then you can blow them off without them knowing who you are. Secondly, it is safe because there is no physical contact right away unless you arrange for it (and in the case of contact, you get to choose the time and place). And last, you get to know somebody before you can judge them by the way they look. Most people say "it doesnt matter what they look like, its whats on the inside." But the first thing a girl or guy notices about a person before they get to know them, is whether they are good looking or not. And, most people find someone with the same level of physical appearance as them. The only downside of online dating is that if you talk for a while, like eachother, and then meet, the person could be a total weirdo. Especially in the guy's case, he could be a rapist or a serial killer or something.
