I have a hobby game up on GitHub. The README explains that it's open source for people to fork it and file issues, but that I don't accept contributions. So far, it seems like that's been very effective.

We don't always have to solve problems with technology. Sometimes you can just tell people things.

Sometimes it may be good not to say anything at all :)

I like the idea of crafting tools that allow the user to accomplish something that would ideally not need software.

Even better if the most prominent feature of a necessarily complex software solution, is the behavior to the user as if it is absent completely.
