On Speed Running and Glitches

This is a video by Source Engine speedrunner Michael 'DemonStrate' Yanni. In it, he manages to complete the game "Portal," which is designed to take the average first-time player about 6 hours to complete, in less than 10 minutes. In order to accomplish this, he abuses several programming oversights with regards to the game's central game mechanic, the portal gun. Upon viewing this video, many people's instinctive reaction is that these glitches are somehow "cheating," without realizing that the abuse of glitches is one of the oldest traditions of video game speedrunning. Obviously, I must correct these poor unenlightened souls.
