One sacred rule is: Do what you want.

No, really. Wanna post shit? Do so. Wanna argue with strangers? Go on. Wanna drop some bomb and disengage? More power to you!

You do not have to engage, you owe your time to NOBODY on the internet. If you don't follow the rules of place you engage in, they will sort you out and that's it. But other than that, you don't owe anyone anything on the net - no responses, no culture, no acceptance, no hate, no lowering yourself to their level, nothing, nada.

That's why the net is beautiful. Wild west. Well, and why companies find net aggravating. xD
