Twitter and Linkedin are huge competitors.

  Twitter maybe, but LinkedIn really isn't, unless you define the market to be "connecting anybody with anybody else on the Internet".

    The market is selling ads. I thought that was pretty plain.

      You should look into LinkedIn's revenue sources. Ads are actually a smaller part of the pie.
