One thing that I've always missed about this site is that the links that people post within pages, link within the page. What I mean is that the links don't open up in a new tab or new window. Several other forums that I frequent have this feature, and it's very useful. I'm able to check out what someone is showing without having to leave the page.
I also have a bad habit of accidently closing out of the window when ever I follow one of these links.
ctrl+click or click the link with the scroll wheel.
