1. Twitter adds ‘Promoted Tweets’ to everyone’s ‘stream’

“Twitter is expanding its promoted-tweets program and is now including paid tweets from companies that people don’t already follow in their timelines.”

2. Facebook introduces the ‘Subscribe’ button

“Hear from people, even if you’re not friends
Let people hear from you, even if you’re not friends”

What’s missing in both these product announcements?
Any mention of the social graph. Any notion of bi-directional digital relationships.

In fact – both of these announcement are completely counter to the interaction model that allowed both of these companies to gain the trust of their account holders.

The giant sucking sound you hear is the ‘social’ being removed from ‘social media’.
