According to my knowledge, Coffee meets Bagel uses the Facebook API to generate date recommendations based on second degree connections. Wolfram Alpha uses connection/mutualfriend info to produce a visualization and some metrics. Are these apps reliant on the functionality provided by v1.0 of the Graph API (to be deprecated in May)?
If so, what will happen to these apps when v1.0 goes dark (what workarounds are they working on?)? Will they lose some of their functionality or do they have access to a super-secret partner program?
What other popular apps do you know of that will be affected?
