I work with Pat and kicked around some title ideas with him yesterday. It's interesting to see a title that he created out of a sense of fun and excitement being perceived as linkbait. I can see why that perception would arise, but I hope people think of him as a good writer trying to have fun rather than some dude writing linkbait titles trying to get attention.
Some other title ideas:
* 23 characters ought to be enough for anybody
* 23: How Twitter could have solved their ruby scaling problem
