Kickstarter is not an investment
In case you haven't heard of it, there's this great site called Kickstarter. If you have an idea for a documentary, video game, or other product you're trying to get off the ground, you can post it on Kickstarter, detailing the process you're going to go through, what you need money for, etc. Then anyone who likes your idea can donate as much as they want. In return, they usually get a copy of the product (if it's something easily copy-able like a video game) or some other little trinket from the creator. For example, I donated to the "Polkadot" book series a few months ago.
Kickstarter, and sites like it, have come up in conversation a few times with people I know. And there is a sense from some people that it's a "scam" because you don't get any real return on your investment. Call me crazy, but I think there's something nice about a donation where you don't expect anything back. You just do it because you believe in the thing you're donating to. Not that you necessarily believe it will become massively profitable, and you want a cut of those profits, but maybe you just believe the world will be a slightly better place if that product exists than if it doesn't. It's a donation, not an investment. And there's something kind of nice about that, don't you think?
