Thanks for posting that - unsurprisingly it has come categories mine doesn't

It raises for me the question of how we capture 'developer helpfulness' for want of a better term.

Case one: dev creates a low level but rather fun widget and posts it to the system. It's fun, demands very little of the user and never needs updating.

Case two: dev creates a complicated but extremely useful app: some users in the tsting stage (and even after) find it confusing. Dev routinely invites them to hop on IRC for a talk through.

Case three: dev has an idea which s/he is working on. User suggests an additiona feature - dev picks the idea up and runs with it.

IMHO cases two and three should get higher karma. But there's no way for the user to vote not onluy for the app but for whether the dev was helpful/interactive etc. Could there be?
