The open crowd - free range crowd? - is populated essentially by non-experts. And in that sense you'd think an expert in the crowd could clean up and win contest after contest. (If you're an expert playing in the crowd let me know about your experiences!)
I've witnessed many winning solutions that are clearly off-brief. (And heavily dissed in the forums by livid community members) The winning solution providers are earnest and sincere in their efforts and often show some extraordinary creativity. Getting off-brief is easy. That's were crowd managers and brand keepers should be stepping up. Hard to do with 1500+ crowd members. We still have account execs and creative directors in the trad agencies that struggle with the task too. And the less precise the brief the harder the task,
Filling all the media channels available to any brand with new content via a regular agency would be cost-prohibitive.
So here come the crowds.
But many of the Cs's vids for brands are painful to watch, proving only how hard it is to actually create and tell a good story in 30 seconds. But the crowds still come and the brand still buys the stuff.
I would suggest that apart from participating in the contest, and reading the brief, no crowd members actually care that much about the brand. How can they? They relationship is not consumer-brand
What drives the crowd?
