Which is absolutely fine. It's their project, their website. If they can't be colorful on their own website, where else can they be! If it turns off some people, I'm sure the author is aware of the risk and happy with that risk.

I, for one, find this kind of colorful language refreshing. Everyone trying to be politically correct makes the internet a dull place.
