As my post was written, I guess I wasn't really qualifying things. I could have worded that a little more precisely. I was thinking of proprietary platforms such as FB, not open protocols like email. If we're counting protocols then I suppose we'd have to include the phone networks and MMS and I think those would eclipse email. Although, I don't think it's useful to compare proprietary closed social networks to open protocols; seems very apples-vs-oranges.
