Tumblr debuted in 2007 as part blogging tool, part microblogging tool, and part social community. Each user has his or her own Tumblelog where they can publish short posts of text, images, quotes, links, video, audio, and chats. You can even reblog a Tumblr post that was published on another user's Tumblelog with the click of the mouse, just as you might retweet content to share it on Twitter. Furthermore, you can like other people's content on Tumblr rather than publish comments as you would on a traditional blog post. Tumblr is extremely easy to use and also works on every mobile operating system.
More Tumblr Features:
You can link your Tumblr account to other social networks you use and you can feed your traditional blog or other RSS feed to your Tumblelog. You can also create static pages such as your own Questions page that people are automatically taken to when they ask you a question. If you want to make your Tumblelog private or just make specific posts private, you can. If you want to track your stats, you can add any analytics tracking code to your Tumblelog, burn a feed with Feedburner, create a custom theme, and use your own domain name.
Who Is Using Tumblr?:
In 2011, it's estimated that there are 20 million Tumblelogs with over 5 billion posts. Tumblr is free to use, so everyone from celebrities to business people and politicians to teenagers are using Tumblr.
Is Tumblr Right for You?:
Tumblr is perfect for people who don't need a full blog to publish lengthy posts. It's also great for people who prefer to publish quick multimedia posts, particularly from their mobile devices. Tumblr is also a great choice for people who want to join a larger community. If a blog is too much or too big for you, but Twitter is too small or too little for you, then Tumblr might be just right for you.
