My question on plugins has reminded me of the failing of a strict Q&A format. The inability to have a dialogue with the people answering the question.
Yes, there are options like chat, email, and meta, but they fall a little short of the mark.
- chat is 'real time' and the participants may be in different timezones, or simply not online at convenient times, making this impractical.
- email is precluded by SE's (sensible IMHO) policy of not exposing email addresses.
- meta is meant for discussion of the site, not the actual meat of a Q&A
So that seems to leave three options - edit my question, post an answer of my own, or open new questions.
- editing the question runs the risk of if being a chameleon question or rendering existing answers irrelevant
- posting an answer with more questions is clearly not acceptable
- Asking new questions ... well then you get a chain of "continued in ..." comments which are very hard to follow. Unless, when a final answer is arrived at all the preceding questions are deleted.
So, how do we deal with this type of issue?
This is a generic problem with SE's format and that's not meant as a criticism.
In this case of the specific question I linked, it's the answers I'm receiving which are both surprising me and leading me to want to refine the question to tease out what I'm starting to think might be a very important corner case.
