I don't have any real experience with open sourcing projects outside releasing a few small things with MIT licenses (none of which had any real activity from others)—so while there's a good chance I will open source this, I just don't know at this point if there are things I need to take into consideration that I'm unaware of. Hoping to get some feedback on that by posting now.
Edit: haha, okay, answering the revised question:
It's roughly the same thing: lack of knowledge of how open source projects 'work'. I guess I have a number of probably unfounded paranoid concerns about what would happen if I were to open source—which I'm actually less concerned about now, but early on I had some ideas about turning the software into a business, and I've had the perception that you need to know what you're doing to run a business around an open source software product.
