This started on this thread, but it was recommended to start a new one.
Ethereum is a rapidly growing and improving technology and sometimes an answer from even a month ago may not be 100% correct anymore, or there may be new information.
I believe that a simple edit will suffice for removing or noting outdated information if it no longer applies. My question is what to do with adding new information as it comes to light.
Is it better to just post new answer (at least while the number of answers per questions is relatively small)? Or the new information appended onto the selected correct answer?
For example, a simple one that comes to mind is backing up Mist. First there was no backup in the menu so you had to go to the folder. Then there was and it was called Backup, directly in the top bar. Now it's under accounts. The top answer shows only one short-lived version (0.3.9) and no longer applies.
I went ahead and added a new answer that was more comprehensive than the original, so just works for this case. However, if the original answer had been super comprehensive, would an edit to add information pertaining to Mist 0.5.1 and noting the versions used in the original answer be appropriate? Or would still just adding a new answer specific to that version be a better choice?
Obviously this is going to depend highly on the specific case, but I would like to hear your thoughts and how you would handle the situation or what would impact your choice to edit, append, or create a new answer.
