This was hard for me to watch, but I watched it anyways I think this was pretty accurate to what happens with online dating. In this arena, you have a lot of people that may not be the most adept at in-person relationships, but they are willing to commit to and follow through with promises from online-relationships. This is an example of that case.
The problem with being online is that you can publish your innermost thoughts 24/7; even at times when you probably should not. However, the person who gets your communication doesn't know the difference between those times you really mean it and those times when you don't.
If you are the kind of person who says crazy things when online (and perhaps a little intoxicated), you should bear in mind that someone might really believe what you said. Because of this risk, if you are someone who reads an online statement from someone, you should take it with a proverbial "grain of salt" until you actually meet the person (if that ever happens). However, if it seems genuine, you should probably follow through with it (like in this movie; I would applaud the makers heartily).
I think I have just added an extra layer of complexity to online dating, but so-be-it. You can always buy me off with an offer of Colt 45.
