Thread: How well can you know someone online?

How well can you know someone's mind online? Do you think it's more or less possible to really know someone online than in person? Why? This can be about friendly relationships or romantic ones. Is it possible to fall in love with someone over the internet? Is it more difficult than in real life or harder? Or does it entirely depend on the situation?

Posters need not answer all of these questions. They just give a general idea of the overall topic.

EDIT: In the poll I wrote "(between slightly and much)", but I meant "(between slightly and a lot)". (The top and bottom options said "much" before but I changed them to "a lot".)
