Question for the audience:

Response rates are falling on notifications, newsfeed items, etc. There’s a point at which it comes very very hard to be viral on top of Facebook anymore – this is starting to be true with e-mail virality, for example.

This roadblock will happen one day, but how long before we hit it? Months? One year? Years?

Folks with better visibility into Facebook viral stats would know better than I do…

BTW, I think this is a great reason for very app developer to be looking at OpenSocial right now, because it’s all green fields, and people who invest the time on things like language, cultural understanding, etc., will have a huge advantage in being able to generate the highest growth apps.
