If you're having fun, fun's more likely to happen.
It's always better to have fun working on a project than not!
For one thing, it's more self-sustaining. For another, fun is contagious: if you're having fun, your audience (journalists or whoever) are also likely to enjoy what you're doing. (Disclaimer: there's probably no research to back this up, but it's true.)
There are many ways to have fun, and what's fun for one person may not be so for another. But one thing that we find increases the depth and intensity of our fun is knowing—or, ok, feeling—that what we're doing is making a difference. We just don't find it fun to do weird things for their own sake, or, heavens forfend, to make fun of those weaker than us. But doing weird things that punch up at oppressors—that's about as much fun as it's possible to have on this planet. (Skiing can come close, but only if you're good but not too good at it.)
