Now that I've got your attention. Honestly, I have no idea, but it will be really amusing to see my google analytics stats on this one, I wonder how much malware gets spread through typos in the most popular web sites. Maybe everybody else allows their browser to get them to the right place, but not me. I end up at some weird sites, or at least sites that people in Frederick, Maryland would consider weird.
BTW, the site above is from dgmail.com but it would be an interesting research project to analyze the content of fat-fingered sites. Sure, most are probably ads, but may be some goodies lurking in there.
