Besides the social site, Tumblr is also one of the best micro-blogging platforms. It is based on short and frequent blog posts, such as a quote, an image, a GIF, short content in general. It is very easy to use, both in terms of setting or customizing the blog, and posting or maintaining it.
One of the important features with which the platform stands out, is the possibility of using any of the free custom domains available. Another major advantage would be the fact that Tumblr can be connected to your social network environments and keep all your ideas synched. This is a favorable thing when it comes to the real purpose of the blog, namely attracting as many followers for your posts as possible.
What needs to be taken into account, is the fact that users can interact with each other and share things throughout the community with great ease.
