Critical mass is key to the flocking principle as well. As social networks become even more federated (linkedin, flickr, mybloglog…) but concurrently develop aggregator-agnostic APIs, I think a ‘lifestyle aggregator’ platform like Facebook makes it easier to achieve critical mass through the applications and services that integrate the many elements of my digital life.

In short, I think OpenSocial aims for this same power but Facebook already does it well and today. Ultimately I think FB and the many integrated elements it hosts will become just another spoke in the wheel of my digitally aggregated lifestyle. The ‘next migration’ IMO will be a function of whatever is most convenient for me in terms of social and commercial interaction.

If I’m traveling and want to find a quick read or movie to download for my flight, I’ll just tap into some aggregated, intelligent [behaviorally predictive] resource that will instantaneously poll my Amazon purchases, iTunes library, magazine subscriptions, RSS feeds, Facebook groups, LinkedIn interests, etc. to give me a list of the most relevant choices. Ergo, as networks evolve into hubs of meshed personal info and behavioral patterns the only migration needed is more of my private information and personal preferences into public spaces. OpenSocial + Beacon + aggregated lifestyle feeds + [rapid advancements in AI] = what’s next.
