I was thinking that if a given question is agreed by the community to be a bug/defect in a technology (e.g. SQL Server, C#, ActiveMQ, Java etc.) then you could provide the plumbing to link us to the defect database for the tag. I.e a link to the MS Connect website, SQL Server page.
If a defect was then raised, you could make it easy for people who get the same problem to "vote" for the defect to be fixed. I.e. update that link to the appropriate defect number in the product's database.
It would be a really nice feature for dev's who hit the same bug, and it would be a really nice way to get Stack Overflow exposure on each of the product sites? I realise though that there is integration to be done here, but I think it definitely fits the being better programmers mandate for SO.
