Examples of hitting the platform risk
Slide built on top of Facebook, but failed to generate “front door” direct traffic
and lost users when Facebook shifted their platform.
SocialCam used the Facebook graph and created an auto-share loop. Facebook
found the loop to not match user’s expectations, and changed its algorithms.
Meerkat used the Twitter social graph to accelerate growth, but Twitter shut
them down to promote Periscope, the live streaming app they had bought.
