Picking a domain name for your new business, product or service is often the most challenging part of launching an enterprise. After all, you want a website that is easy to remember, does not have too long a name and will stand out among the crowd of websites on similar topics. The process of picking a name is complicated by the fact that so many domain names have already been taken.
