Not everyone has English as a first or even second language. No bothering because of spelling seems like a good way to filter out some cool pieces of code.
Sounds like a good way to filter out a certain kind of users.
With some potentially unreadable documentation. Spoken language is not less important than programming languages (and interestingly, from my experience, there seems to be at least some correlation between caring about either).
I did not spend too much time writing the documentation because of the simplicity of the library. I thought that the tcp echo example would be enough.
But I'll spend more time in the Readme, at least fixing the language issues :)
