Applications to search for domain names there are many, but to check the availability of social networking profiles very few. Many people use the same username for each service, network, blog or website, so consider that these aliases are part of their identity and are interested in knowing that others are not in use.
NameCheckr is a web application that will allow us to search for a domain and its availability in the popular social networking sites, a handy tool to see if that username has been used in social networks or domains.
With so many social networks and blogs is common to find the same people with the same user names in all services, to link them to your other accounts, such as a Twitter user @twitterers in FourSquare also use that name, because looked to their Twitter followers also continue in that network.
While not required, ideally within the virtual world that we live there is any order or notion of reality and it is important to maintain the same credentials on sites that use.
