Hey wait a minute. The expression RL as in "Real Life" is just a joke phrase that has entered common word usage on the Internet. It just means anything that isn't on-line. It doesn't in the least imply that life on-line isn't real. That's part of the joke.

Taking jokes litteraly is um....a bit special...Or maybe someone got a humour tumour.

I'm sure nobody thinks that the people posting aren't real people. I promise you all that I am very much a real person, and anything I do is really real. For real.
