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:

1. Making existing problems and their answers easier to navigate through the use of tagging and a stricter question-answer format.

2. 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.
