I've been writing some articles for a domain-sales site, and researching how short names are used, I found some funny ones.
Pink.com is a girls/teens/young women's site.
Blue.com is not a boys' site, though. It's some spiritual thing with a weird, hard-to-understand-what-the-heck-it's-about text all over it.
Click on Hers.com, and you'll end up at His.com. Just figures, doesn't it.
TLC.com is owned by Disney. I thought that was nice.
Puzz.com is a puzzle site.
Puzl.com is sort of, too; you design your business site there. You put all the pieces together.
Buda.com is owned by a guy who does financial services all over Europe. Why the name? He's from Budapest, it turns out. And is possibly homesick.
