- Grass-roots efforts with enough publicity to get them to reconsider.
- Well-thought-out proposals for integrating Notebook into other Google services like Gmail, Gcal, Gdocs, etc., and somehow getting their execs to see the light.
- A polite plea to sanitize the Firefox extension's code of anything proprietary and then open-source it, so it could be integrated with another service.
The other idea that has been floating around is an online petition.
What I find most interesting, is not the number of people who appear to be upset with this decision, but rather the level of intensity, commitment, and excitement users had about Notebook. These are the users every software company fawns over.
A well-publicized grass roots effort may have an impact. I will be giving more thought to how to pull something like this off ... IDEAS are welcome.
