It is well known that the domain names registration has became an industry and some people are making big money from registering or purchasing domain names, developing websites and/or selling or reseling them to others. Beside these people, the main reason of purchasing websites is the someone wants to develop a business or a network of sites and somebody else registered a desired domain name.
It does not matter the reason you are purchasing the website, always check the trends when you are decided to make the step. Even if you are already sure about the domain name you want, the TLD market is always changing, as long the people are pressuring the Internet authorities to release new TLDs. You can always find the free domain names on different TLDs if the primary domain name is already taken. I’ve head some time ago that there was taken a decision about registering the TLDs freely, as you want, but I’ll have to check it out (to update my information) and I’ll post another article about this story.
