Internet

Why is it that so many people rely on the internet these days? I remember the days where the internet wasnt always relied on, but now i know kids the age of 16 and up that use it to find friends and relationships and thats all they do. I remember being able to walk down the street run into someone and say " Hi would you like to go to a movie or hangout?" Go to social events like footy games party's and what not and meet new and interesting people. But now its all "Have you got such and such?" or "Whats you email and i'll add you to my friend list." What happened to askin the person for their phone number or what they are doing the next day or night if their busy or not? But i guess i cant really talk because i am now relying on the internet myself to find a relationship...i just hope i fint the right girl for me :)
