Yahoo! Answers is the latest entertainment site I found. Once you get there, it's very hard to quit. Take this guy for example.. trying to contact an air hostess :)
Worldmate is the perfect travel companion. It's a subscription based application wich also includes some free features. Excellent for every travel, though I would recommend the PRO features only if you really need them and only if you travel by plane. Otherwise there's no use paying for it.
prettyloaded.com is an archive of preloaders. The preloader archive is growing each day and it's becoming more and more a hard to close website. I never thought there will be a website dedicated to these stuff that you hardly pay attention to and that keep you excited while a page is loading.
