As a UK-centric term, (compared to US) due to differences in language, it's limited in geographical scope - but that suits the .uk extension (I think using .org.uk and then .uk when better known, not .co.uk, is the best route).
The issue is what to do with it, building a decent resource on it would be a huge task (due to the size scope of things that even just procurement covers for the public sector).
I like it, but fear it's too difficult to develop for people to want it that badly.
