I am thinking that Twitter has reached saturation for the most part. Pretty much everyone has heard of it and has an opinion about it. The areas of the world that do have an untapped audience also have authoritarian regimes that do not like Twitter very much.

At the same time, there is some manager with a spreadsheet that has new account creation metrics. S/he wants that number to be as high as possible. How do you do that if people do not actually want to make an account? Try capturing the people who usually click in from other sites and bounce back.

I think the end result will be that social media somehow becomes even more pictures of text than previously.
