Replayability is a word

I just read the (2010) blog from ben abraham (lowercase from his blog name "ben abraham dot net"), "`Replayability` is NOT a word, so stop using it idiot!" I feel the need to reply to this, because it's a concept that I've come across before, and I'm kind of tired of dictionary thumpers. I don't want you to get the wrong idea, however. I'm glad that he wrote this article. It shows that he's at least thinking about what the video gaming community is. That's a good thing. I just think he's wrong about his conclusions.
