I thought of @Arif's point when I read this quote:
"The idea that Twitter is a behemoth that can’t be overtaken is shortsighted. They shouldn’t be afraid of upstarts, but not because upstarts aren’t threatening. The reason they shouldn’t be afraid is that they should already be pushing toward what’s next. They should have a vision for what the future of communicating and sharing looks like, and be building it. But from the looks of it, they aren’t. They’re just trying to protect what they’ve already built. That’s always a losing position… Always. ALWAYS."
- Chuck Skoda, on Twitter's future
Twitter has fallen short of it's promise in many ways and has, for some, turned into an RSS feed of their interest without conversation.
