I have to disagree with you just a bit, spark...
Diversity of tactics means just that: diversity.
We need all kinds of actions, including the big peace marches that we both find kinda boring. But just because you and I think they are boring, and waste tons of money on unecessary permits and "free" speech rights, doesn't make them useless.
We should be embracing each other's tactics and supporting each other, not arguing amongst ourselves. "Radical" marches (although I would hardly call yesterday's march radical in terms of tactics or message) should be more inclusive of liberal folk, and the big permitted marches should encourage more creative forms of direct action. Instead, posts like yours (and similar posts from the other "side") have polarized us into two camps. This divide between "good" protestors and "bad" protestors will work great for the cops when they decide to attack us.
Let's not do their work for them.
And one thing that they do better is organization.
From another rant of mine:
Clearly, we do not need permits. But we do need a little more organization. Yesterday's action was pretty good, but could have been so much better.
If someone had actually worked on publicity (making/distributing flyers, telling KBOO, other stuff) there might have been 3000 people instead of 300. I believe it is pretty irresponsible and lazy to call an action by only announcing it on Indymedia.
If someone had done some minimal logistical support we might have had a bullhorn or two for the speeches, street medics to help deal with the pepper spray, and copwatchers to document cop crap.
If people had agreed on a plan, we might have gone somewhere with more of a political point than shutting down the entertainment district.
We do not need permits, tons of meetings, parade marshalls, etc. but we do need some minimal organization.
