I’m not so sure that the site name matters as much as it once did, so long as they’re minding their search engine rankings. http://www.bubble.com is a Google site. http://www.bubble.net is available, as is http://www.bubble.co, but honestly how many people even think to use anything but “.com” if they’re just guessing a website URL or going from memory?
My dentist wanted me to build him a website, but he took the name restorteeth, with restore missing its ‘e’. Always thought that was a mistake.
