Can this be a statistic that shows up just on our personal profiles? I'm not really comfortable having that number next to every person's profile. It makes me feel like it has some relevance to the poster's credibility, and I really feel the amount of money someone's contributed to the game shouldn't impact the value of their opinions.

I'm fine with this being some thing we have the choice to go out of our way to look at, such as inspecting another user's profile, but it being so overt makes it difficult to ignore. I would also add the option to make this a hidden value by default. Those that wish to disclose how much they've donated have the option to do so, but it's something that requires input.
