Can a group get too large or formal for ICA to work?

"The old way of doing things, you could think of it as there are three steps in the campaign process," Ruben said. "Step one, listen hard to what members want. Step two, figure out what we can do on that. Step three, turn around and kick that back out to folks and say, 'Ok, if everybody stands on their head on Thursday, we'll get health care,' or whatever the strategy is that we've come up with. So the game here is to take that middle step, which is really the leadership step, and hand as much of it over to members as possible."
MoveOn will still weigh in on elections and other national issues, said Ruben, but the new bottom-up approach will mean much more attention on local issues.
"It's a huge shift and definitely a risk, but it's doable and we feel like it has the potential ... to dramatically increase the number of successful progressive campaigns and projects around the country and to give us a much more clout in these big national fights that have already been our focus, like a big election or the fiscal showdown," Ruben said.
Ruben cited a grassroots-driven campaign that originated with a Pittsburgh member who used the group's new petitions software, called SignOn, to urge local elections officials not to implement an illegal voter suppression law. Campaigners working for MoveOn latched onto the idea and helped spread it across Pennsylvania, running paid media and a traditional campaign against the law, which was ultimately overturned. MoveOn's campaign team, Ruben said, would have never thought to urge local officials to oppose the law, but breaking out of the Washington box allows more creative thinking.

    ICA only works with a simple goal and no leadership.  So when does a group last so long that ICA should be tossed for more formal organizing?  Can a group be too big or diverse for ICA to work?  What exactly are the boundaries where ICA can be successful?  These questions I hope will be studied.  In the Case of Moveon.org, they appear to believe that they can more closer to ICA than they have been. That's pretty interesting.
