I looks at it like this. If starting companies were easy everybody would have one. Sometimes things don't go as smooth as they looked from the beginning. As long as I know that it's not a shell company, and that their is actually product being tested, then I know the company still has the possibility. When I see a filing that says we are no longer testing any product in the field, and that we no longer have any product to test, that is when I'll call it a failure. Even if it takes 5 more years which in that case I would expect Kay to adopt to fit the current technology, or bow out.
It's a pink sheets company. Companies go public for one reason only. To sell stock! Companies never have shareholder interest in mind unless they are giving a dividend.
Companies know shareholders are only here for one purpose only, to sell stock. Companies know shareholders are only here to buy low and sell high, unless there is a divvy involved!
Good luck to all stock holders, and stuck holders!
