I find the exit link feature in the new Shoutbox quite annoying, really. ;c We made it years without one, and being suddenly forced to it makes clicking links in the Shoutbox seem like such a ha-ssle. Sometimes I don't even click on them because I know I'll just have to go through all the opening another tab and clicking it and closing the exit link's tab and.. yeesh.
I know, it's for security and I'm just being lazy, but having that laziness taunted every time I click a link, thus making me click less links, makes me.. pretty useless to the community. I'm not doing the buying, the helping, the looking, the laughing, the anything that I would be doing otherwise. And it makes me feel a bit left out, when I think of it.
Heck, the security thing isn't even really all that big for everyone, since some people do know how to see what's through a link before clicking on it.
