Basically, this is just the lament of the early adopters realising that as a space gains more and more users, the more it begins to reflect the mainstream regular person. That's okay, in my opinion, and I disagree with the premise of the article. Personally, I still get tonnes of value out of Twitter. I follow a lot of people I admire, and a lot of my friends, and my Twitter feed has none of the toxic bickering that it's come to be known by, so I disagree that Twitter has crossed a precipice and can only ever be a negative force in your personal life. But, hey, that's just like, my opinion man.
