Besides the content of the thread, which is interesting, you'll notice if you scroll through that the thread is added to periodically, whenever the author finds a piece of information that adds to the theme of the thread. This is an underused but valuable way to use twitter. @grayconolloy maintains several of these threads and builds up arguments that can contain years worth of contributing information.

While any thread could be curated to make it look more prescient or more predictive or more correct generally, these threads do demonstrate the overall effect of being able to compile a realtime and longterm "story".

Twitter's most innovative or emergent uses never managed to be useful for most users, and the canned attempts to deliver what people invent have been unsuccessful for the most part. The main reason why to my mind is that it takes literally maintaining a list somewhere of "long-term threads", and remembering which posts to post in which thread. No one does this, but for many in the news-media this would be a valuable way of piling up information into a coherent narrative that people could always "unroll" or whatever.

Please comment with the obvious twitter features that I'm not mentioning. I really don't use it very much anymore and nothing recently has jumped out at me either as a feature or as a feature that people use and promote that replicates this functionality.
