WHAT IS TUMBLR?
Tumblr is a simple microblogging platform and social networking website. The service is very similar to WordPress and Blogger but has gained a following for its ease of use allowing users to easily post text, images, videos, links, quotes and audio to their “tumblelog”, a short-form blog. Users also have the ability to follow other users and ‘reblog’ their posts.
Tumblr allows users to easily customize everything on their page, including colors, images, and access to your theme’s HTML.
With over 42,000,000 blogs the service has seen tremendous growth as well adaptation by large media sites, who have created a Tumblelog aside from their full fledge website.
Tumblr is a free service.
