I've found that Twitter's business model has and is straying from what originally drew a lot of users in. I started using Twitter because it was a great source for real-time updates from people I admire. I think it lost its mojo when it became more of a social network where people stupidly try to have conversations in 140 characters. That drew in the trolls.

One thing I've always found odd is that the companies who provide me with a valuable service, like Twitter, refuse to charge me money even though I would definitely pay. I pay for magazine, newspaper, Netflix, Google Play, and Amazon Prime subscriptions. I would more than gladly pay for a Twitter subscription. Instead of trying to appeal to everyone, appeal to people who are willing to fork over some cash for what you have to offer.
