Is it really "just the internet?"

Something just occurred to me. I see folks neglecting their online contacts like they are just "internet connections." But, are they really? I mean, I have never planned on speaking directly with anyone I've networked with on the internet, but I never rule out the possibility. The idea that maybe, that person you connected with on Twitter, or any number of other social media sites, could turn out to be a FRIEND? Your future boss, perhaps? A great collaboration somewhere down the line, or simply someone to get great advice from. Imagine that! Is it really "just the internet?"
