I think you need to be a bit more firm on the rules for it. Maybe even give people a contract...
If you mean protecting myself, I don't think the people who would buy into this are going to scam me. If I were going to be selling some low-margin items, I'd probably be more concerned, but I just don't see it as an issue honestly.
Interesting experiment. The danger is you get a handful of takers, then you have to live forever with the admin overhead of keeping track of them (as they change email addresses, etc. over the years), all for a little temporary pocket money. I guess that's why you need to say things like "I'll do my best." Maybe you could add a condition, saying the deal will kick in once X number of people sign up, otherwise everyone gets refunded.
I'm going to look over my post and see how I can improve the message. Thanks.
Statistically, that's an incorrect statement despite the best wishes of all present.
You also failed to present anything remotely resembling a sane value equation. The only product of yours that the mass market would've been interested in, you managed to crash and burn.
You're not exactly offering anything in return for the money at the moment, and you don't have that large of an audience either.
Not even Joel would have had the gall to try something like this.
