What's in a name?

While I do not suggest ignoring tools such as pqR, coq or gimp because their childish and immature names, I do think it is bad manners to name your tools in an offensive way.

It also makes people talk about the bad name you choose for your tool instead of the properties your tool, and surely that's not what you wanted, as a creator.

If you want your tool to be considered a professional tool used by professionals, please name it like a professional would. If you want your tool to be used by children, by all means, name it like a child would.

I think it's unreasonable to expect the namers of a language to know every conceivable double entendre in every language. Coq was named by French researchers, and means "rooster", and pqR is obviously from the sequence of letters. Neither of those seems particularly immature to me, in context.

Yes, it's the sequence of letters but that's not all. From the first line in TFA, "pqR — a “pretty quick” version of R."
