I just posted a summary of the current data portability landscape to the Official DataPortability Blog. From the post:
Closed platforms are like ice cubes in a glass of water. They will float for a while. They will change the temperature of the liquid beneath. Ultimately, however, the ice cube must eventually melt into the wider web.
Facebook’s success with Facebook Connect can and will further drive innovation in the community to develop an open alternative.
Facebook’s success will (like Google, Microsoft and Yahoo, AOL, Myspace, countless major media properties and countless small startups) to create alternatives. At least some of those participants will recognize (if they have not already) that the most open among them will earn both the respect and the market share of the next phase. Moving from Facebook Connect’s ‘data portability’ to Interoperable DataPortability.
A web of Data.
That’s a landscape where we can continue to innovate on a level playing field.
