Im always interested in buying stuff with my bitcoin, but when the seller is on the other side of the ocean, it rarely makes sense due to shipping/taxes. So the vast majority of offers dont interest me, and I can usually only find out after actually clicking the topic and reading it.
Therefore I propose that forum be divided per continent or economic block (US/EU/Asia/other or something), while also having a "global" section for those purchases where buying across continents can be sensible.
I dont think there is a point in doing all these in the existing forum. AFAIK the new forum is coming in 2015.
