Although, at this point it's mostly just spam, porn, and political bots at really really low quality. Imagine the day when worthwhile content with journalistic, artistic, or intellectual value is posted by machines. There are already some great bots pumping out tweets with color palette, non-sensical invention patent ideas, and historical events.

One way to cheat at this is to use existing intellectual discourse as a template, and simply swap out nouns/verbs with other ones, and change the structure slightly perhaps using Markov chains.
Another way to appear more credible is to generate sources to backup your statements. Wikipedia is full of links and footnotes which prop up their entries. All that's needed is to scrape these and use them for your natural language generator.
Just wait until you have a tweet-reading bot that picks out the items most interesting to you. Arguably, we already have that in the form of Facebook's like-driven echo chamber algorithms. But it would be nice to have a version whose parameters are under your control rather than some large organization with questionable motives.
