You are not investing, you are donating to an experiment. If it is successful, you will be very well rewarded. Thus, only donate (invest) what you are comfortable with.
Also, your time and your treasure(content) is another way to donate to the project.
It is fun to have a passion (hobby) in life.
If you put money anywhere expecting a return, then I consider that an investment. If've seen stocks wind up at $0, and that wasn't considered an experiement.@magnebit, donations don't ever come back except as good karma or if enough was given away a placard/name tag on some wall.
Thanks. I guess I still don't see the point if the potential exists for me to get rewarded exponentially higher for posting alone than anything I could ever afford to invest .
