It is my perception at this point that management has tended to an optimistic view of how long things take, perhaps because their engineers have themselves produced so much so quickly.  Now they rely on other companies/customers and have also been hindered by geopolitical problems, and I honestly think they've been surprised and disappointed themselves by, well, how long it's taken.  
I have regretted some of the ugliness that was on this board that resulted when expectations weren't met, these last few years.   Some people couldn't just express their thoughts, it's like they turned it into a war instead of a discussion, and had to 'be right' - so it was repetition that used superlatives and ridiculous accusations that, if they believed them, should mean they themselves could not possibly be shareholders in this company.  
Back seat drivers always think they can do better.  Look at Apple getting rid of Steve Jobs!  I think Suresh is a very capable smart man, who has shown he can pivot when needed to.  He is the driving force with the vision that has produced a remarkable platform.  He is the one determined to make Poet into a large company.  I personally think he can do it.  
I am indeed looking in the mirror and kicking myself for my outsized position in Poet, but in the end, I am choosing to trust Suresh to finally fulfill his vision, so I'm holding.  I hope management can listen to our fears and hopes, and remember how many of us are 'pulling for them' and for Poet. 
In the meantime, fellow shareholders and readers here would do well to consider that some of the posters here may be gleeful shorters.  Readers beware!
