I have seen a lot of people still using Blogspot and Wordpress free hosting in the Entrecard site. This worries me because a lot of people might end up having issues trademarking their name or a certain logo in the future.
Having your own domain is better than having a free one because it allows you to have more control over the things displayed on your site, it also allows you to buy a certain word, or keyword.
There really isn’t much difference between a free blogspot/wordpress site, than a self hosted …
