Twitter is a publishing platform. You go there for (links to) news, blog posts, commentary on particular subjects (some of them very niche), notifications of events or live reporting of something happening in public.
Why does every form of communication have to fit the mold of "keeping in touch with friends and family" and match the user numbers that these services inherently deliver?
I'm so fed up with the dominance of "keeping up with friends and family". I have better things to do than to "keep up" with pointless brain farts and daily routines of people I know.
And why is everything measured by what kids or teenagers do? So much so that people on here pride themselves of "getting" snapchat in spite of their advanced age (>30) as if that was difficult or any sort of achievement.
The salient feature of teenagers is that most of them haven't yet found anything that they are deeply interested in. Most of them don't have very complicated social relationships yet as they don't have a past with anyone. They are not held accountable for anything, and they don't have to make well informed or consequential decisions yet.
In other words, their demand for information and communication is hard to predict but can often be met by something totally inadequate for others. So it's not about "getting it", it's about finding it unfit for purpose.
There's a pattern in the demise of Google Reader and Twitter's current problems. It seems to be difficult for internet behemoths to justify investment into the significant but limited niche of people with advanced information needs.
I wish Twitter had the courage to try to increase usage, utility and depth instead of growing user numbers. And no, it's not an inherent problem with capitalism. There are many successful, publicly traded companies that do something useful, make a profit, and don't grow much.
