Facebook is Microsoft. Twitter is Apple. Ironically, that’s exactly how it may pan out.
Microsoft is a Facebook investor. Apple may soon count itself as a major Twitter investor.
Facebook doesn’t get along with Apple. Twitter could care less about mediocre Microsoft powered devices.
Facebook is about mass, a hoarder of the world’s global population. Twitter focuses on its rabid 140 million strong user base to spread the global message.
Facebook is ineffectively monetizing mobile ads. Twitter makes more money on mobile devices than its desktop.
Facebook design is clunky and inconsistent across devices. Twitter design is pretty much the same on computer, mobile, and tablet via its standard roll.
Facebook embraces mutual relationships. Twitter is a public forum.
For Facebook, more of everything is better. For Twitter, less is more.
There are clear and deliberate philosophical differences between Facebook and Twitter, much like there is between Microsoft and Apple. Hardware and social behavior mimic each other.
The arms race continues.
