For questions which have standardised straightforward responses, i completely agree with merging and closing duplicates. The difficulty is that some of these discussions start off asking the same questions and end up in quite different places.
@alexs 's FAQ is a really great point of reference, we’re working on putting together a much more comprehensive FAQ section for the website over coming months.
Having created pinned posts for bugs and travel, (two umbrella categories which I think a lot of these threads fall under) I would feel that that in time, the number of duplicates will fall for two reasons. 1. With some regular housekeeping, people will be able to find the solutions to their questions much easier through these threads. 2. Old duplicates which haven’t been replied to will automatically archive after a year (I could also look at possibly reducing the time before a post is archived, maybe 6 months?)
Overall I think one of the most unique and appealing aspects of our community is that someone can access relevant and timely answers from a welcoming and knowledgeable user community at the click of a button. For me, it’s amazing to see and I’d hate to lose this through managing interactions too rigourously.
