meet up vs chat over apps

Ever feels that behind the hi-tech apps you could chat so well with the person on the other side, but then when you meet up it just seems like both are on different section of the bookshelf? Guess this is why there is nervousness of meeting up. But if meeting up doesn't give you much to talk why would using sms or man be any easier? Most likely the emoticons. Looks like we would need to do better than to expect more in a meet up in that case there would be no disappointment.
