I just build things for myself, so I know the demand. I call it me-ware. Works for me, and once or twice it also worked for others, but if it doesn't, that's fine, too. Of course I don't charge anything, I just release it as FOSS.

The thing is that figuring out how to realize an idea is the fun part. Making it into a polished product that others can easily use with proper documentation is as important as it is tedious and exhausting.

i love the term "me-ware". I've done that many times too! my interests are too weird so no one's interested in the projs i'd do.
