Tumblr

Tumblr was founded by David Karp and Marco Arment in 2007. Tumblr is a "micro-blogging" website that allows users to post mixed-media content. The seven general categories of content Tumblr users can post are:

• Text
• Photo
• Quote
• Link
• Chat
• Audio
• Video

Posts can be sent to your Tumblr page by directly visiting the site, via an internet capable phone or email. Tumblr registration is quick, easy and free.Official Site: Tumblr.

Tumblr users can follow other users, receiving their recent blog posts and content.

Similar to Twitter and Wordpress, Tumblr allows you to centrally update your page with fresh content at any time in a user friendly blog format. Like Facebook, Tumblr is the central location for your personal momentos such as video, audio, photos etc.

Unlike other social media and blogging sites, Tumblr offers high levels of interactivity and content sharing for all media types. Not only can you post your own content onto your "tumblelog" but you can easily insert other blog posts and share media content from limitless sources. You also have the option to upload content and media files directly from your computer, rather than placing it somewhere on the internet and linking to it.http://www.fastcompany.com/blog/chris-dannen/techwatch/what-hell-tumblr-and-other-worthwhile-questions
