I would like to have discussions, myself. But being non-math minded, can't get into any in-depth formula banter. ;)
How-done-its would be good--but with so many different proggies out there, it would be difficult to say "Well, you push this button and get that result..."
What's left is critiques...and that's more an artistic judgement call. Composition, color, etc.

For example, I could say something like: "I don't generally like to do the 'traditional' Mandelbrots and Julias, preferring to explore the fringes of a fractal, where discontinuities and isolated elements occur." Would that start someone else talking??? (We'll see. Stay tuned, same frac-time, same frac-channel...)
