“This past week the Better Business Bureau listed the company as being ‘out of business,’” wrote Brian Dolan of MobiHealthNews. Dolan also said the company’s CEO appeared at a TEDMED event last week identified as the former CEO. “While there is no official announcement, no known buyer yet, it’s clear that Zeo as we knew it is now over,” he writes. The company’s Twitter account has been silent since the day after Christmas.

Whether or not Zeo is totally defunct (the company did not immediately respond to an e-mail seeking confirmation), its apparent demise raises the question of how big the market really is for self tracking. Does anyone outside of a small niche of obsessive geeks really want all that data?
