Not to the extent that you don't listen to your members for everything but you shouldn't be letting stories get to your head. Contrary to popular belief about what you're doing with the revenue RG is generating, you shouldn't be worried about what others believe to be happening. As long as you know matters are under control and you're taking care of maintaining the site, you don't owe it to anyone to prove us anything.
You do your thing and we will do ours. If there are a few odd-heads that just so happen to think poorly of your investment protocol, this forum is as easy to leave as it is public and accessible to all. If you waste time on insignificant battles like this you'll be running around in circles trying to please everyone and that's nearly impossible. Hypothetical situation; if you were to be spending RG revenue on your own well-being, it'd be perceived as bad management. On the other hand, if you'd be working to reinvest every penny generated from RG back into it's prosperity and to ensure its continuity, there will still be people that will be jealous of your success. Either way you go, you can't satisfy anyone.
Do your thing and leave it at that. Again, you don't owe us an explanation. Let them whine all they want. If these people you speak about aren't happy with the way things are run here, no one is holding them back.
