Favorite conference panels?

Coming up soon it’s panel time!

Next weekend I’ll be moderating a panel at SXSW:
Community Ecology: Finding Balance When Working with Fan Groups

Then it’s off to Vegas for Community 2.0 where I’m a panel member:
Community-Based Innovation

All this panel discussion has kicked off some thinking about the best panels I’ve seen over the years.

What are your favorite panels? What are the greats, the ones that stuck out to you?
