Review on Coral by Lance Harrison

I like that it is completely free for individuals to use (no credit card required) but paid if you want more than one user per profile page or multiple pages in your site! If someone uses an account with another person who has previously created their own website using coral then they can be added as "friends" so sharing links between sites/pages becomes easier too.

It also allows people from many different countries around the globe connect easily online without having to learn complex language barriers etc.
