If you're asking because you want help with some network programming you are doing in Haskell then you can PM me on some kind of social media.
Write it as a reference that even you'd find useful, with emphasis on defining the basics and getting them right, and increasingly lighter when it comes to intermediate and advanced concepts. Those can either form future books or consulting or both. Since you've started writing, it's worth it to go through the whole process and publish. I did it with a conventional big publisher some time ago, but I wouldn't do that again today. The idea a big publisher would require you use Word is very familiar to me, and I think it's ridiculous.
