I would rather focus my attention on a broader survey designed not only to gauge interest but also to foster inclusivity and find what skills and ideas people have for the community and what can best make them feel welcomed and included and matched with projects that can use their skills. This has to happen on both the technical and non-technical aspects of Solid. We want a diverse a group of people building the tools and and a diverse group of people advocating for the technology. I think it would be a mistake to say that either is more important than the other, although I agree with you that we are weaker on the advocacy end right now.
As you know, solidproject.org, is both a website and an organized community, headed by Sir Tim and with a variety of teams that work on various aspects of the project. All teams are open to everyone though some positions on the teams are by appointment of the director. The newest team Solid Diversity, Equity, and Inclusion Team (DEIT) is in the process of creating a survey to answer some of the questions posed above. I encourage you (and everyone else) to join this team. Start by visiting us in the DEIT gitter chat room to discuss broadening the participation in Solid with diversity, equity, and inclusion as guiding principles. Ideas for the upcoming survey are welcome.
I also think that it would be great if there were a team focused on advocating for the technology and promoting legislation supporting our vision. Perhaps rather than a general poll, you should ask who wants to be on that team with you. Come to the next solidproject.org team meeting and brainstorm how such a team might fit in.
