Buying a domain for a website you only want to play around with can cost you a few bucks along with the hassle of avoiding automatic charges. Getting a free website and hosting from wordpress.com can be quick and easy but it is not the same as having your own domain on the Internet. I found out that there is a top-level domain sponsored by the Government of Tokelau and Teletok that offers free domains and have used their service on multiple sites (like manandkeyboard.tk). Registration is easy for the domain and you can easily point your new URL at your existing website or you can use a service like 000webhost.com that will let you host your own website. The added benefit of setting up a host is that you can make custom emails like your first_name@last_name.tk. With your own domain, you easily impress people by giving out your website or personalized email.
