Because it was suggested this should be taken to meta. Context of the situation was "Rigs might need a warning label on his posts" and he wasn't aware this forum has signatures until someone pointed it out. In that specific context, him having a warning label that he speaks in lawyer terms and bear poking is probably a good thing. I happened to broaden the signature thing above, saying a decent amount of people have information in their signature that explains some of their habits (missing replies, not wanting to be pinged in certain places, etc). The problem is signatures aren't on by default, so a lot of new users unaware of the habits of old ones aren't going to automatically see these things. I was on the forums for months before I accidentally discovered we had signatures (I turned them on for a little while but ultimately turned them off because uniform feeling. I'm unsure if I would have turned them off had I not already been so accustomed to not seeing them). If siggies were on by default, then people can see these "warning labels" people tack onto their posts before turning them off (if they do at all), and it gives others a little breathing room by not expecting them to remind people every so often that "hey can [x situation] happen please?" (like people want Rigs to do with his flame fanning sorts of replies). I get that the custom titles can do the same thing, but I'm also much more aware of signatures than I am custom titles (because I associate titles with silliness, like the "angel names" some people have, and as such my brain is WAY more inclined to completely ignore the thing by glossing over it). With signatures they're immediately under the post, so your eye will catch it as it goes on to the next reply.
