I know that this sound hopelessly naive..
... but where does the money go? I know where it comes from (idiots with more money than sense and, I imagine, money managers who get a percent of the money invested, not the return on that money) but where does it actually go, once Twitter gets it?
"Twitter's data licensing and other businesses also showed impressive year-on-year growth."
They wouldn't by any chance be "licensing" that data to various government agencies, would they? If they could just be a bit more intrusive, they would have more "data" to license, and more money to, you know, burn through.
As someone once said, although in a very different context, "What a world! What a world!".
