I did. I didn't notice the "dwagon" until it was pointed out to me and I still don't see what the fuss is about. What difference does it make if the occasional w is present? I can't possible see how this "childlike" substitution of letters constitutes either a certain type of humour or detracts from the overall humour of the strip.The childish humour of Erfworld, by contrast, is intrusive; evidently some people like it and some don't, but either way, you can't ignore it.
Tell me, are there really people that can't/won't get a joke when the word is not spelt "correctly"? I can't understand that at all.
