[I_]

Was about to say this. Though less useful, because Partiful doesn't require an app so can be used by anyone.

I wonder how much the network effect may be leveraged for apps like these, to the benefit or detriment of apps like Partiful in comparison with Invites.

I know Facebook's last useful feature appears to be events in many circles.
