Cuv pointed me to a page entitled How to Write Like a Wanker, which is most amusing. I quote:
No matter what Flash-blinded web monkeys would have us believe, the Internet is a text-based medium: especially its major discussion forums (IRC and Usenet) where people from all over the world can interact and share information.

Nothing could be further from the truth.
