I support whatever choice you make, but I don't think that you should put pressure on yourself. You don't need to take on the weight of redeeming anyone, let alone trying to counterbalance potential wankers who might be involved.

It's up to you to decide what's best for you, but my advice is to only contribute if you feel you have something to express and that this project is the way you want to distribute it. Not participating does not mean you've been silent (you have a journal that people read) or that you've let anyone down. You are real. We can only guess about the possible audience.
