Dale Larson wrote an interesting blog post on the rise of Twitter and its position versus other social networking platforms like Facebook. Larson writes:
The moment I was introduced to Twitter, my eyes got big. I saw something simple, different and open. It was already evolving through user behavior and through the addition of connecting services. It could be a kind of underlying protocol, the hub of an ecosystem, not a stand alone website.
To me it is just not the openness of Twitter that is so inviting and absorbing, it is its adaptability. Twitter works with so many platforms and devices. It is ubiquitous.
