almost no one is "techie" enough to do those signatures, or verify them. Yes, it's easy, but almost no one knows how to do it anyway.
The point was to have the option as in "optional".
But yes. I agree with:
I usually just read the messages here, and barely glance at who wrote it.
To me the important thing is what's being said, not that much who said it.
I was just worried about other people. But as the discussion in this post showed me, I don't have to. It's not my problem. And if there ever comes a time where it is important to verify someone, then I can still verify someone myself.
