When a site is in commitment phase, why are the example questions locked? I would think refining the scope of the site would be a worthwhile activity, during all phases of the project. As it is now, you can't really do much about the project during commitment phase.
Because the "definition" phase is, essentially, done. Users are asked to commit to a proposal based on a series of questions shown to them when they digitally sign it. It doesn't feel proper to have that page change dynamically, after the fact.
A lot more definition work can be done during beta. Go out and evangelize the site and get ready for the beta. You'll have more than enough time to contribute improvements during the real discussion… in beta.
The current process naturally goes like this:
- define the scope through the description; as a guide, a title doesn't always say enough.
- refine the scope through the example questions, see the requirements for that phase.
- commit after the scope has been defined & refined, so that the right people join.
- improve the site once in beta, through meta discussion as Robert C. mentioned.
