There are a lot of different societies.
Most of what we think of as “society” is actually an amalgam of different societies. This is what we do in public in order to make lives easier. (We don’t go around naked, we don’t use objectionable language, we bathe, we pay for things…) However, there are a lot of different societies all around us.
Think about not just where you work, but the industry you work in. If you were in a room full of people in the same industry, you would be able to talk intelligently about the work, because it’s similar. That same discussion would bore your family to tears unless they were part of that industry, of that society.
When you join a society, it’s best to learn how the society conducts itself. It may be best to sit back and watch for a bit, or stand up and introduce yourself and start interacting. This will be the best time to learn what the society wants from its members.
A society always wants some measure of conformity of its members. By conformity, I mean conformity of actions, not just a like-mindedness. The more granular the society, the more conformity is expected.
For comics, the big society is doing work in comics itself. That comes with meeting like-minded people, doing the work, getting known. Then you start to get granular: print, digital, or web? Then you start to get even more granular as you gravitate to different types of comics you want to do. You may find yourself joining a forum of some sort, like Penciljack or Digital Webbing. You may go someplace totally different, like Comics Experience. These are the main places you’ll end up if you’re creating comics.
If you’re a fan, you may find yourself at the CBR forums, or at a forum hosted by a professional. Just understand what these places are looking for in their members, and your time in that society should be smooth sailing. Don’t be like the so-called “internet trolls” who are there just to cause trouble. Their fates never end well.
