It's easy to take networking for granted; just plug your PC into a modem or router (or, ahem, "find" your neighbor's wireless connection) and voila, instant Drunken-Facebooking. If you're old-school and remember a time before teh interwebs (think the acoustic-coupler modem), however, then you get excited about different ways to connect one computer to another. What's even cooler is stuff like tunneling, virtual private networks (VPNs), and encryption. Yes, really. Oh, shut up, you know it's cool.
