Is it acceptable to edit my answer to include something said in another answer? This problem came up in this question: What is the best technique for long-exposure photography in good light?. My understanding is that we want the first answer to "say it all". What do you think?
The software on which the site is based has proven itself where there is a single correct answer. If you've skimmed over a side detail, then I would encourage editing to include more into your answer. It's worth remembering that all content provided is licenced as cc-wiki with attribution required, however.
For questions that are inherently subjective (i.e. there is no single correct answer), then perhaps we should be (strongly) encouraging the asker to flag it as community wiki - I believe then it removes the question from your percentage of accepted answers too.
