I think AU was a genuine trial participant with some very interesting information to share. (S)he did not seem to be a very sophisticted investor and apparently does not understand that MNKD's success depends on much more than the efficacy of Afrezza, and that the company faces major financial hurdles.
That being said I fail to understand why people on this board cannot simply put forward their viewpoints and leave it at that. If I claim that 2+2=5 do you really feel compelled to debate me until I concede that I am wrong?
I think a statement of your point is sufficient and there is no need to "win" the argument. Certainly AU has information to which none of us has access, and I for one was interested in hearing that information regardless of any other unsophisticated ideas the messenger may have had.
