It is a verification that the user is who they say they are. Or because they'd like to communicate with people using pgp (gpg). Many good reasons. I'd actually like to see it more in online forums.
I understand all that, but I wouldn't call them "good reasons". It's a throwaway comment that has absolutely no extra weight no matter who says it. Unless you have reason to believe that Hubski's security has been breached and someone is impersonating you it's needless and distracting. And even if he did believe that, this seems to be the only comment that DarkLinkXXXX has ever signed, so we still wouldn't know that it's the original DarkLinkXXXX based on this one signature.
I do agree it's distracting. That's why I relegated the signature into a paste in a pastebin, linked to at the bottom of my comment as I usually do. See: All my comments since a couple days ago.. Do I need a reason? I used to have some fun being a script-kiddie by dumping SQL tables, and there's a lot of vulnerable sites out there. Not to say that this site might be vulnerable, but the nice thing here is that I don't have to trust the admins of any website to keep your online identity secure.it's needless and distracting.

I do agree very much agree, but there's only one problem with this: it's too many steps! First, I have to copy-paste my comment and sign it. Then I have to put it in a pastebin, copy the url, and then link it in the comment below. That's simply too many steps for most people. Though, I am optimistic about keybase maybe making a secure API to make the process easier.
