Thanks Pine -- the team appreciates public discussion on our plans!
1. Budgeting: You can see how we map strategic goals against the teams from the Roadmap document above and then refer to the annual plan docs to get an idea of relative investment. A couple of caveats -- sometimes the activities don't totally matchup with the teams; for example some folks from Android are working on services. Also, while we have general metrics for the various strategic goals, we are still working on more specific metrics and targets so we can be clearer on expected and actual impact for investments. (It's a good question and probably something we should be more specific about moving forward)
2. Mobile Editing: We work closely with the Editing team and they are investigating mobile editing features for the following quarters. I'm afraid I don't have the goals URL handy but they should be posting shortly. However, we realize that editors are also readers and we will also opportunistically identify activities that help editors (user profiles on mobile for example).
