I wonder about that too. It seems like they could write a blog post somewhere else, like Blogger or Tumblr or their own blog, and then link to it from Twitter?

I wonder about that too. It seems like they could write a blog post somewhere else, like Blogger or Tumblr or their own blog, and then link to it from Twitter? That was how Twitter first came into existence, was to link to content that was elsewhere. Perhaps the author feels they would lose their audience if they tried to send people elsewhere? That would be somewhat ironic, if we got to the point where people were unwilling to follow links from Twitter, to other sources of content. (I'll refrain from making a joke about all the Russian bots that really have nothing better to do.)
