A few points:
1) the caller was "Ken Rybicki" who is a known entity on the YAHOO board as well as on several earning as Q&A sessions. They know who he is. He conducts himself like an #$%$ each time he calls (not just to current mgmt but to Glenn as well) or when he posts. I applaud coming at the Mgmt team with hard hitting questions but don;t be a jerk or disrespectful and think that's being a "tough interrogator" or furthermore think you are going to get the quality of response you are aiming for. I personally believe the delay between Ken's question and their response was them all looking at each other rolling their eyes and saying "great this #$%$ clown again"
2) Bob and perhaps Bill as well spoke about the message boards and how it's wild west of misinformation and Ken began his usual preamble with stating YAHOO and the message boards are his main source of info. That's just funny IMHO. It's sort of like discrediting yourself from the outset.
So I don;t think Ken caught them with their pants down. This question has been asked before and Bill has responded. The truth is their personal business is just that. I certainly would like it better if I saw them all buying in but in the end it's not informing my decisions re: position on this investment. my two cents..
