A) the question asks specifically how to find a "side project" idea, not necessarily a full fledged business all though it could turn into one.

B) The whole point of being involved in a specific community (e.g. fantasy books written by Terry Brooks) is that issues will crop up naturally that you, as a dev, may be in a position to solve. Theorizing on problems in this thread is the exact opposite of my suggestion.

C) The topics were half in jest (see 'armadillos'), and were just meant to kickstart the OP's thinking process.

The process of coming up with an idea shouldn't have to happen in a vacuum. The point it to solve problems you encounter and help solve them.

You're totally right. Just frustrating -- Guess if I want to do something in that space, I need to get more involved in the community, like you said in "B".
