Just pointlessly trying to exist way past its date of expiry.

Facebook reminds me of Edison pushing his DC power distribution model on everyone. Telling the world nothing else will work. Trying to get them to build an Edison Power station every second block. Coasting on momentum built and wasting everyone's time. Spending huge resources buying out/maligning/litigating the competition. But it all fails. Few people ever needed DC power distribution. At the end of that story Edison says after a series of humilations in public and finally loosing control of his company "I have come to the conclusion that I never did know anything about Electricity".

That moment for Mr.Zuckerberg is fast approaching.
