I think your sentiments resonante widely and with many. If TM 'retired' today I wouldn't forsee any negative impact to the company or its investors. Perhaps the contrary. Yes he has overseen some recent fundraising programs but I don't believe a CFO deserves acclaim simply for carrying out the job of a CFO. The track record from day-1 has not been wonderful, and continues to be an impediment IMO.
Anyone ever see the video of John Lennon and Chuck Berry's duet on the Mike Douglass show? I feel like those are our rockstars and TM is Yoko Ono.
