At least where I am from you must go and cast a vote privately alone on paper. So this can't be executed on big scale, you could only force couple people to cast a specific vote without getting kicked out or arrested.
It depends. How about, do not use one step to verify/authenticate/authorise/etc - Period.
Biometrics is not a password, so it should not be treated as one. There are many good advantages of using fingerprint to do something where passwords would not be great.
Take for example a public place - do you really want to enter your password/pin when somebody is looking? And with current levels of video surveillance somebody is always looking.
I'd rather place my finger on my phone and unlock it. This goes with any method of authorisation - we should focus on making sure people are aware of their strengths/weaknesses, instead of using scare tactics saying something just doesn't work.
This means code review process is completely wrong. All these "nitpicks" should be automated by linters and code review should be more about implementation, structure, performance, etc..
Awesome guys, really nice and fast funding process (though if payment fails you are stuck with plain red message in blank page, you could improve on that one).
The advice I can give you - steal best parts from Kiva, they have great and successful site. One of the things I missed was "tip" donation along with the treatment donation.
