A few highlights of our thinking:

* Marketshare for Facebook based on their self reported "500 million active users".
* Marketshare for Instagram based on their reported registered users, using the same ratio as Facebook from registered users to actives.
* All other market share stats based on the reports form quantcast.com.

When you think about social media, does this ring true for you? If so, why / why not?
