tumblr. is a microblogging platform that allows users to post text, images, videos, links, quotes and audio to their tumblelog, a short-form blog. Users can follow other users, or choose to make their tumblelog private. The service emphasizes ease of use.  According to comScore, Tumblr scored 13.4 million unique visitors in the U.S. in July, 2011 — up 218% from July, 2010. As of May 1, 2011 Tumblr included more than 5 billion total posts and over 17.5 million total blogs. In June of 2011, Tumblr surpassed WordPress in total number of blogs breaking through the 20 million mark. In August 2009, Tumblr’s CEO, David Karp, was named Best Young Tech Entrepreneur 2009 by BusinessWeek.

Tumblr followers and users have shared the reasons why they love using the service on various platforms. The following are the reasons why Tumblr has recorded billions of posts.

  1. Not only can you get some already beautiful templates on which to build your Tumblr page, there are dozens of free and paid ones out there put together by some very creative designers.
  2. I like it because it’s more free form than other blogging sites I’ve tried.
  3. I like the pretty/funny pictures people post when my poor university-fried  brain is too exhausted for more reading.
  4. I like it because most people on there aren’t judgmental of anyone (unless they insult their fandom lol) and it’s hilarious.
  5. I like that there’s people over on Tumblr, and random people stumble over to my photos and “reblog” them or indicate they like them.
  6. I  love reading other people’s blogs. Some make me think, some make me laugh, some make me cry. It’s very personal and supportive.
  7. Simple, easy interface. I like that it’s so simple to post photos or text, and I can do it from my phone or the web.
  8. Tumblr supports a wide variety of other posting methods as well.
  9. You can create posts via e-mail or SMS message sent to a special e-mail address, or by sending an instant message via AIM to TumblrBot.
  10. Sharing content is also central to Tumblr.
  11. Tumblr also lets users “like” posts, and you can also “follow” people whose blogs you like to read.
  12. In fact, I don’t know how Tumblr could be any easier to use. Want to post a video? Great, just drop the embed URL into the “add a video” area, hit post and you’re done.
  13. The Tumblr dashboard acts as a stream, and pulls in all the content of the people you follow. Only instead of 140 character snippets and links, there are pictures, quotes, videos and posts all in one place.
