I feel like I want to:
a) allow for hashtags in the post title and content area, and get rid of the group input on new post. Also expand the number of tags per post from 4 to a lot more, maybe infinite.
b) Get rid of private groups, I don't really use those and it would simplify things. Or maybe keep them and rethink the setup and initialization. For example, they could be a hashtag that starts with #! like #!mytag.
c) Get rid of the following moderation system and use a normal admin moderation system
