Great Question. I just think that along with the social aspect of a local group, the group should mainly provide feedback and help. I have of course tried to speak about what I do to improve the world we live in.
The problem really is that (at least within this group) new ideas are extremely rare and do not get a lot of reception. It is more like a echo chamber of confirmation for the group members. I am very unsure wether I should bother CEA with this since it might waste their time as well.
