https://meta.stackexchange.com/questions/90573/error-on-stack-exchange-data-explorer was posted (and quickly marked as a dupe and deleted so 10k only) and was a dupe of StackExchange Data Explorer bug (PRIMARY filegroup full) which is cool, cos people don't always read, but so I tried using the title from the dupe as the header for a new question, and it didn't show the dupe-original in the list of proposed related questions.
The point I'm making
The Related Questions query seems to need some loving. Won't you please love on the Related Questions query so that it can faster find the more recent posts as well as the more upvoted ones?
