No, I would never recommend this. The nicest people you know may not be so nice on the internet. They could have any number of habits (porn, terrorism, abuse, media stealers (torrents, p2p), illegal fetishes) and etc. Or, they could be gamers and suck all of your bandwidth up. Any of that is bad news for you.

You would be amazed. I used to be in IT and I was constantly amazed at how different people are in their online life than they are in real life.
