Tumblr is a blogging platform that makes personal publishing easy. It allows you to create content and post it online. I have one myself. Yep you can even use your own domains. If you know what your doing you can even become pretty popular.
The content you can share include Text, Photos, Videos, Quotes, Audio, and even Music. It really rocks. It's simple and can be done from anywhere using a mobile phone.
