A Google Chrome extension/plugin/thing that locally and privately tracks a user's website and media consumption of participating Bitcoin economy content providers, and presents the gathered data to the user. The user can use this usage data to help determine consumption patterns and inform bitcoin donation decisions. Content providers will likely have to add a metatag or similar line of information indicating their participation, how they wish to be identified/recorded on the user's database, and a donation address for the associated content.
I've never created an extension/plugin/thing before, so it will be a long time until anything remotely useful is available. But I like technical challenges, and this is one of the first ideas I've had regarding the usefulness of bitcoin in general, and am increasingly frustrated that no one is implementing this kind of ecosystem building infrastructure/browser tools.
Please let me know how much the idea sucks and how I am totally failing at implementing it properly.
