It’s not your goal to make paypal.com paypal. w/e, it is your goal to present the opportunity therein. You should/can’t never start a company this way similar to the main business. It is your goal to A. – sell the domain, B. Monetize it like with a forum where people can come and discuss about that business/service. Paypal . w/e sits on the same SEO potential at that point of magnitude as paypal.com, it would be wrong for search engines to discriminate by domain extensions so I think I’m correct.
