"To talk about Stewart’s theory, you have to first tackle the ideas of the 20th-century philosopher of media, Walter J. Ong."
No, you really don't.
That said, Twitter's never made it easy to digest its content. Sure there are lists, and now moments, but it's not always easy to find what you're looking for, and if you're not really careful about curating your own feed and follows reading twitter is like some sadist's idea of an exquisite corpse.
It could be that people don't feel comfortable with everyone having access to what they have to say. It could also still be as simple as not really caring what other people have to say.
Perhaps Buzzfeed type listicles are more your speed then? Every time there's an article like this posted on HN, there's inevitably someone who posts, "Fewer words! More facts!" (Bonus points for you for getting in a dig about them useless Humanities!)
A thesis isn't right or wrong; it's presented and supported. It's an idea. This is literary journalism. Some people, myself included, enjoy it.
The most compelling argument for me was about context collapse. Shifting between spoken-word contexts and written-word contexts is at the core of the issue that requires a feature like moments. Spoken-word contexts lack an explicit connection to the events they discuss and require manufacturing a context. I think moments has been great at doing this so far but its existence is a symptom of the bigger problem.
In the final paragraphs of this article, let me assert something I have very little data to support: At some point early last year, the standard knock against Twitter—which had long ceased to be “I don’t want to know what someone’s eating for lunch”—became “I don’t want everyone to see what I have to say.” The public knows about conversation smoosh, and that constitutes, I think, a major problem for Twitter the Company.
I don't think I agree with the author's conclusions about "conversation smoosh" causing the decay of Twitter. Would love to hear any rethinkings/clarifications of the author's points, as I found them near inscrutable due to the convoluted structure and logic of the article.
