I found that variations on the following exchange are very common on programming forums:
Alice: Programming language feature X is misused more often than not. It’s bad.
Bob: Every language feature can be misused. That does not make it bad.
Suppose Alice is correct on the statistics: most code that uses feature X uses it in a way that Alice and Bob would both agree to be wrong. Suppose Bob still disagrees with her over it making the feature bad. He disagrees not because he thinks the good uses outweigh the bad ones but because it is possible, in principle, to only use feature X the right way. Is there a specific name for their kind of disagreement?
Less Wrong and its comments are a treasure trove of ethical problems, both theoretical and practical, and possible solutions to them (the largest one to my knowledge; do let me know if you are aware of a larger forum for this topic). However, this knowledge is not easy to navigate, especially to an outsider who might have a practical interest in it. I think this is a problem worth solving and one possible solution I came up with is to create a StackExchange-style service for (utilitarian, rationalist) ethics. Would you consider such a platform for ethical questions to be useful? Would you participate?
Possible benefits:
Making existing problems and their answers easier to navigate through the use of tagging and a stricter question-answer format.
Accumulation of new interesting problems.
The closest I have found is http://philosophy.stackexchange.com/questions/tagged/ethics, which doesn’t appear to be very active and it being a part of a more traditional philosophy forum might be a hindrance.
Edit: a semi-relevant example.
