The news is coming fast and furious on Open Social. I think Mike Arrington puts it best with:
Suddenly, within just the last couple of days, the entire social
networking world has announced that they are ganging up to take on
Facebook, and Google is their Quarterback in the big game.
I can't believe how quickly this all came together. Apps that have built on a single DB on Facebook must be drooling at the chance to provide a unified, cross property experience.
Are widgets even relevant any more in this app dominated landscape, or are they just a quaint precursor to the virality and functionality enabled by API powered applications?
