I do think that you should point out in any discussion if you have a specific product or vested interest which is relevent to the issues at hand, even if your profile links to your company page. I am not having a go I just think its a good idea - given noone checks the profile of every single person that posts to a thread. By no means am I implying any improprietry on your behalf - I am certain you are completely above board, I just think its a good idea in general.
