Are there any good trust, value, or reputation metrics
The first problem is defining what do you want to measure. "Trust" and "reputation" are two-argument functions and "value" is notoriously vague.
For clarity, I meant "trust" and "reputation" in the technical senses, where "trust" is authentication, and where "reputation" is an assessment or group of assessments for (ideally trusted) user ratings of another user.
But good point, especially for value systems.
This thread is for asking any questions that might seem obvious, tangential, silly or what-have-you. Don't be shy, everyone has holes in their knowledge, though the fewer and the smaller we can make them, the better.
Please be respectful of other people's admitting ignorance and don't mock them for it, as they're doing a noble thing.
To any future monthly posters of SQ threads, please remember to add the "stupid_questions" tag.
