I posted this in the comments of the article; but what I would like to see is a link between Google+ and Android Market such that each application I publish creates a dynamic circle. The dynamic circle would contain anyone that has installed my application, if they have chosen to allow it.
Create a system-wide setting in the Android Market around whether to allow this and then if someone wants to get more granular they can use Google Plus. Their email would be masked so that I could not see the address but it would let me contact my customers.
I think this would help address some existing issues while giving Google's android market a way to be very different from the existing app stores.
I also think using +1 on the Android market (especially the web one) will greatly help with app discoverability. Just imagine +1'ing an app on your phone or on the web (maybe after you install it?) and then your friends being able to see it.
But I'm not so sure about you proposed. Google needs to be very careful here and not turn Google+ into a spam fest of apps, the way Facebook has become. Google's main priority should always be the user, not the developers here. And as they said, Google+ should be much more about life-sharing rather than sharing how you got 5 more coins in some game, or whatever.
