Only other example I have is also far too old to be of use to you for demonstration purposes... the old "Accurate Shooters" forums. When there were 5 forums, it was a lively place with high traffic.
Eventually, it was spit into ten... then fifteen.. then thirty or more sub-forums. Traffic died off, users left. Eventually the place closed down.
It was shutting down about the time I started on Dealmac....

What was behind the impetus to whittle it down into more and more fora?
