I had my first experience with IRC at 15. I'd recently discovered fansubbing and wanted to find subbed copies of the yet-un-aired in America episodes of Sailormoon. Some of the guys in my C++ class were avid IRC users and suggested I get on to see if they were available.
Unfortunately, one of the first things I noticed was the rampant use of the N-word. Not especially inviting to a young black girl. I asked the guys what that was about and they suggested I just ignore it. I had enough to deal with at 15. I never went back.
