Are tags supposed to reflect questions only, or should they reflect both question and answers? Should one update the tags if the thread comes with an answer that brings in new solutions asker didn't know to ask but answers indicate so?
I have always worked on the assumption that tags reflect both the answers and questions. More on questions than answers, but still even answers benefit from searching (after all people searching probably look for answers). It is just that i have never actually put any thought into how I really should have been operating.
