On the first day, God created ftp. And it was good, although rather cryptic and hard to use for many years.
On the second day, God created IRC. And it was good, despite starting the whole l33t speak thing.
On the third day, God created Hotline. And it was good, although banner servers and message bots quickly made it a pain in the ass.
On the fourth day, God created Napster. And it was good, until the RIAA got involved.
On the fifth day, God created Gnutella. And…it wasn’t very good, but people seemed to like it.
On the sixth day, God created BitTorrent.
And it was so damn good, he took the seventh day off.
