Some threads on meta are about making a collective decision or require action by the community. For example, there is the plan of reviving the blog or the proposal of creating our own security challenges.
Both projects have in common that there doesn't seem to be anything happening right now. An issue with the blog seems to be that nobody is assigned to it or feels responsible/entitled to pick up the work. Concerning the security challenge idea, I'm unsure at which level a proposal to the community can be considered approved. While I'd love to continue with the idea, there has in my opinion not been enough feedback to justify pressing on with it. So it will eventually just float around, maybe without ever being concluded in one way or another.
That's why I was wondering how decisions in the community are usually made and what could be done to ensure that projects like the blog revival don't stagnate. I feel like questions on meta often ask for a community consensus or concrete action but just attract a few opinions and then slowly disappear without an apparent conclusion.
Edit: Another example of an undecided problem might be the career tag issue. The community acknowledged that career questions are almost categorically opinion-based but didn't come to a conclusion what to do about it. Hence, users are still falling into the trap of asking for career advice.
