I'm probably not clear enough in the blog post: The intention is to use Twitter as a news source, i.e. crawl and index top URIs (which can be any type of news, blog and other content). The underlying idea is that URIs on tweets give a good sample of _all_ overall knowledge production per day.

There are also of course some benefits of having all the interaction happen between you and your device that I haven't talked about in the blog post, e.g. increased privacy (no data collection), lower latency (disk seek on a mobile or tablet SSD - 100 microseconds) - is roughly 1000 times lower than the latency of accessing 3G or 4G can be (up to hundreds of milliseconds)
