Exactly. We can build up this illusion in our heads about someone but that is just what it is, an illusion. It's like falling in love with an actor. You don't really know them since they are technically playing a part. Did you fall in love with the writing, the character or the actor's looks? It is all very two-dimensional.
Not everyone is an actor, or lies online. Some people of course
do create an illusion. I would say they are not the majority however. It is not at all easy to consistently hide your true nature, not unless you are a psychopath. Some people may be exactly as you read them, what you see is what you get. I believe it's perfectly possible to fall in love with someone's ideas, and the way they think and conduct themselves online. You can post considerately and respectfully, much as you would behave in real live, or you can be a dick, like you are face to face.
I do think you certainly have to meet before you can cement any feelings, absolutely. I do think it's somewhat unfair to have low expectations of everyone you meet online. Of course, it depends where you meet. I would assume dating websites are a hell-hole. You would need to get to know the person slowly over a long period of time in different online situations, to give yourself a chance to assess the other person, and to be sure of yourself enough to meet. Otherwise you could end up playing carelessly with your own feelings and those of others, by raising false expectations.
It is possible to give a LOT of information in writing, both consciously and unconsciously. I wouldn't dismiss an online love-affair so easily. I think it will become more and more the standard for romantic relationships to be formed online. So much of our daily lives are conducted online now. A lot of people would consider it no different than meeting someone at the post-office or a long train journey.
I would say though, that an online love affair is a gamble, unless you are very very cautious. Similar to a holiday romance... most will fail when the glow and the infatuation wears off, but a few will be based on truth and depth and stand the test of time.
And hey, how come I don't get masses of creepy love-letters, too!? Chance would be a fine thing.
