To kick this off: I feel this section has absolutely no value to me. Note this is My opinion. Not a generalization.
I live in Canada and it is rare to find any shops in this section for Canada, let alone my geographic area.
Even if I travel to the USA, finding shops through here that fit me is a hard process.

In a perfect world, I would love to have sub section in here. Possibilities:

Canadian shops
Wide ranging USA shops (i.e. spread of a wide geographic area)
Individual US states

It would be more difficult for MSC to post because they might need to post several jobs in different sub sections, but for the shopper, I think this would make the Job Board much more valuable.

Disclosure: after a couple of months of wasting time looking at this board, I never look at it now.
