Yeah, you have to know your strengths and weaknesses, and he was simply not meant for unguided, unscripted live presentations, at least, not by himself - he needed an experienced, lively interviewer at the very least to guide him, keep him on track... There's a level of charisma that you need, and being able to "wing it" on-the-fly without a script, etc. Few people possess such abilities... It also seems he did this on the 1st or 2nd take, when he needed MUCH MORE practice...
Poor example, but recent is the Kevtris and GameTechUSA project and that recent video where clearly GameTechUSA is much more comfortable, less nervous in front of the camera... It would be very hard to watch without GameTech's enthusiasm and focus.
Anyhow, yeah, it's all amateur hour here and coming from guys asking for $2 million dollars makes it an even bigger joke... :/
