I received dozens of pull requests when my count-words article first came out, almost to the point where I couldn't keep up with them. Thanks for all the submissions!
However, I'm not taking new submissions anymore, due mainly to the amount of time I've spent on this already. The major languages are there, and many minor ones. However, I'm still open to receiving feedback -- you can either email me (via the email address on my website) or open an issue here. Thanks!
