What is the rationale for not allowing answers during the definition phase of a proposal? My naive understanding of this phase's purpose is that it helps define the topic and audience for a proposed site, and I would contend that candidate answers and tags contribute to that almost as much as questions. Were there solid reasons for excluding answers and tags from that phase?
The same question could be asked for the commitment phase as well, and for this one, I would suggest that being able to answer questions during the commitment phase could help build a knowledge base that would be extremely useful during the beta phase, especially if the commitment phase is to go on for several months. It should not serve as a substitute for the beta phase, but I like to believe that some middle ground could be found during which commitment is properly assessed, while a body of knowledge is being prepared.
