Over at the MozillaWiki, they’re asking users for ideas about what features to put in upcoming versions:
We are currently in the early development stage for Firefox 3, and would like to collect all the ideas for feature enhancements in a single place. Our goal is to create a single index that lists what sorts of things we’re thinking of doing, with links to more detailed ideas about implementation specifics or concerns, and targets for inclusion in the project.
This is a smart approach, and one that more enterprises should emulate.
