This topic is less relevant to these forums as you also offer free domain hosting which the others do not.
However, for those working on improving site ranking might find it useful to sign up for this or similar services to create a greater online presence through backlinks at multiple top level domains
For instance, an animal rights group, with a TLD of say animal_rights.info could get a subdomain animal_rights.mooo.com that points to animal_rights.info
Maybe you host a blog about movies, but you also run a game server. Instead of having game.my_movie_site.com you could have enemies.strangled.net
Also, if you use this service to host a top level domain you can choose to keep it private or share it publicly with other afraid users, which means other people can build subdomains on your domain which should also increase your organic search ranking.
What makes this service so neat for me is that they have nearly 1 million top level domains to choose from for subdomain hosting.
Also here are the referenced posts for anyone interested:
Also including a link to afraid.org free domain registry. Check it out maybe you'll have a great idea for a subdomain for your site.
