Drupal Answers is a great resource, but a lot of the archive is not relevant to Drupal 8.
Searching for answers is troublesome, because much of the content is applies to earlier versions of Drupal and it can be very difficult to determine which content might be useful.
There are tags for 7 and 8, but these are often not used.
In trying to make my questions for search friendly I have sometimes prefixed it with D8: This idea it turns out is futile because a StackExchange regular will come usually along and edit it away. (Please don't get me started on the mods editing my questions).
I think this is a genuine issue and expect that many users will agree. So what can be done to make information relevant for those interested in a specific version?
As for me, I think prefixing a question with D7 or D8 or otherwise including the major version number in the title is the way to go.
What do you think?
