Don't we? Don't you have to apply for an Ubuntu membership, telling about how you've contributed?

See [details here][1] about Ubuntu membership. ([This question][2] might also help, as well as [this meta question][3].)

I think users who have contributed **extensively** on Ask Ubuntu, even if they aren't significantly active anywhere else in the Ubuntu community, surely would be eligible for Ubuntu membership.

However, I should add that usually membership is granted based on contribution in multiple areas (see [Marco Ceppi's meta answer][4] explaining this).
