The reason I maintain a presence on multiple communication platforms is because each of the platforms in the above image excels at a specific type of communication.  Twitter is great for very short text-only messages intended for a large audience.  Tumblr is great for sharing images and videos to a medium-sized audience.  My WordPress blog is where I share lengthy articles or images I’ve made myself, and usually fewer than a couple dozen people see each post.

Instant messages, text messages, and email are usually directed at just a single person.
