Its always good to own as many of the popular extensions as you can for your domain. This not only stops your competition from creating a similar site, but more importantly stops some average joe from getting one of the other extensions and starting a completely different type of business, which might confuse potential clients.
For example. We own the majority of the madRooster TLDs. But there is a very popular restaurant that uses madroostercafe.com in Milwaukee, WI is often confused with us. We get inquiries quite often through the website and social media about how they thought we were a restaurant. But as our official business name is madRooster.com we have also trademarked the name as well as the capitalization of madRooster, so that no other madrooster company can display the name like that.
