Seems like kickstarters are mostly okay with the risks.. it is inherent in the site, after all, but man, it doesn't seem necessary to be mean about things..
Some variation of this happens in HK, where everybody wants to learn English (because they can't learn as well from their peers, unlike other subject) and English lecture/tutoring places pops up all over the place, and the top teachers teaches, via video conferencing, hundreds of pupils at once. I'm told the top teachers gets paid in the millions.
If you have no moves, you lose. (You only have a king left and can't move anywhere with it) I actually learned this first, so imagine my confusion when I played western Chess and someone told me now it's a tie!
The other big gotcha is kings cannot have a direct line of sight to each other. Unfortunately, this is how I inadvertently lost a game of western Chess because I had accidentally ported over this rule in my head.
I run "algorithmist.com" and was getting quite a bit of spam with using only recaptcha. I was looking for something mathy.. I ended up giving mathcaptcha a go first and it seems to work well to stop the spam, but I was ready to create my q/a with algorithm questions, with the benefit that if you can't answer basic algo questions, you shouldn't edit the wiki anyways!
I think it's important for students to have critical self-feedback alone. The problem with tests (generally) is that it's feedback for the student (which is good) but also feedback for the teacher, with grades with implications. So basically you have to get everything the first time, and to pace and time that is tricky.
I do like your approach, as it does not penalize you for trying hard, even if you reach deadends, or made some assumptions that can be sniffed out easily by a test. My physics professor did a variation of this sort, where the final consists of all the topics, and your previous test grades gets overwritten by the final if the final grade is higher.
I have a few friends who are in business school and the sole reason they went back (undergrad business in Stern) was to network a little bit and make connections. In terms of class and learning, they knew going in that there was not much to offer.
I'm going to business school (enrolled yesterday), and did so because I noticed that even though I'm much more qualified than some colleagues, they're getting ahead because of their connections.
And I believe it's a human fact of nature and understandable. (also, qualified doesn't mean I actually am a better fit or better worker, just that I studied more).
My reasons for going for Business school are that if I show that I'm hardworking, qualified and an acquaintance, I can shoot for the jobs above my current "glass ceiling".
If it fails or I'm so inclined, I'll go the startup/enterpreneur route :) (I'll probably try both shooting for the CTO position and enterpreneurship on the side)
