It's easier for me because you can take your sweet time with replies, and really give some thought into what you are saying. You tend to get to know people better than in a hectic real-life situation. And if it's the first time you talk, not having to see that persons face, or worry about how you look at the moment, etc, really helps out.
Statistically, I have about three times the chance of falling in love with a girl that I first talked with for sometime on the internet, than one I met in a bar/café/school/work/whatever.
