We have a good set of J examples on rosettacode.org. You should feel free to copy and paste them when you need a cookbook approach to something.
And, you should feel free to ask questions about them if you want more explanation. (Also, some have comments on the talk page - though of course having comments and having relevant comments are not always the same thing.) There are some other sites out there (alioth comes to mind) where people also might be able to have fun and leave behind a record useful to others. That said, keep in mind that internet sites do not last forever. So if you feel like publishing a book or something based on a website, please feel encouraged to do so. Ethically speaking, you will want the website owner as a collaborator and you would want some fraction of the proceeds to go back to the website. But for people wanting some more pocket change and with a writing background, this could be a good way to go. Also, economically speaking, you will want to write something that's fun to read - a little light hearted humor can go a long ways, here.
