What you're saying is inherently incorrect. "Usefulness" of content is always going to be more limited by 140 characters than it would otherwise be.
It worked, not because people want to "share" less, but because they want to read less. Same reason a lot of people browsing Reddit for example only browse it by glimpsing the headlines. The more news there is, the less people are interested in the details of the news - they want to let their brains fill in the details.
Say, for example (and please don't read too much into the example), you read an article that says "Police shoots an innocent civilian". Then a few days later, you read another article very similar to it. Then another. At some point you stop reading the article and you just glimpse the headline - filling in the details yourself, even if they are wrong. You do this for every article you come across, and you enter a cycle where everything you read ends up fitting your own learned narrative. Your brain autocompletes the content of every article... and if there is no match, you can just ignore it.
This sort of behaviour is something you see a lot of on Reddit. People are attracted to short snippets of information they can autocomplete. Most don't want to spend a lot of time on something they might be reading on the toilet, or on the subway. It's the same reason mobile toilet games are racking in millions, while the PC gaming market is taking a major hit.
