Just a personal observation, but I would encourage people to never buy an extension other than .com, .net and .org. The main reason is because the search engines don't really recognize other domains very well as being credible, and if you want good search engine places, stay away from all other extensions. This is the reason you never see a .us or .info at the top of Google or Yahoo. Can't say I have ever seen that. I also know first hand that it's impossible to get one of the those domains to show on Google. If you develop a website with anything other extension other than the main three extensions, it's a complete waste of time. I suppose that's also why .us and .info's go for so cheap. I'm not saying that a fool might not buy them, but if you plan on putting a site on it, don't even try to put a site on it, at least if you want an internet with your site.
