Here's another interesting social website - Tumblr. Learned about from webproworld. It seems to be catching up on its popularity. Since it is free I just sign up and have a go. As a social blogging platform I think it is much better than Vox. And you can use a Android app for mobile blogging on the go too. in addition you can plug in your subdomain to give your website better standing in SERP. I'm going to explore this Tumblr blog app and see its feature for awhile.
