I'm not telling them how to run it... I'm stating what I would do if I were in their shoes...
Personally, I care because I enjoy having a place to show off my art to people who can appreciate, critique, and be inspired by it. I enjoy seeing OTHER people's creativity. There are tons of awesome people here who are a blast to just chat with. Tons of talented graphic artists, musicians, programmers, writers, producers, etc.
For one, I find it sickening for a mod to see that people are trying to stir up some activity and just have it thrown back at them with a nice "IF YOU WANT ACTIVITY, !@#$% OFF AND MAKE YOUR OWN FORUM."
