TBD.com founder Robin Wolaner announced today that the social networking site will shut down by mid-July. “We thought we had raised sufficient money to get us to a sustainable business, but many factors changed in the 2 years since our launch,” she wrote in a message to membes. “As you have no doubt noticed in the past few months, we lacked the resources to continue developing the product to meet the needs of our community.”

Wolaner launched TBD.com in 2007; the name is short for “to be determined”—a reference to her  faith that baby boomers are embarking on new adventures in life.
