He's still working and too busy to do more

Or maybe he's collecting a nice ghost paycheck that gives him time to work on Culbertson Ventures, where he lists himself as a principal and handles duties like:

Currently providing consulting services in the area of Web / Software Quality Assurance and Testing.

Develops and enhances the software testing process to include quality assurance in the software lifecycle, key deliverables expected from QA, issue tracking system and process, test plans and scripts, and all relevant types of testing.

Assists in software implementations, customer/help desk suppport, and providing training to customers.

Experience developing and reviewing product documentation; reviewing proposals, websites and written communications.

All speculation based on one guy's Linknedin profile are what-ifs with no basis whatesover.
