Yes! Of course your experience provides insight to those of us starting out or in the midst of things. Many transpeople learn and get much needed inspiration from those who came before us. That's not to say that we will always agree or share your view, but that doesn't mean you don't have anything to offer. You have a lot to provide and hope you will stick around.
Having said all that, you shouldn't stick around if you feel it's detrimental to your own sense of well being or happiness. I know some people that have finished transitioning that want nothing to do with our community because they just want to move forward and stop focusing on the past. There is nothing wrong with that either.
