Jeremiah Owyang pointed to a sad story on Twitter this morning. A flashmob organized on Facebook for a waterfight at Millenium Park in Leeds, UK. The resulting storm of 350 people completely trashed the park, and the reputation of social media enthusiasts. There’s an obvious way for people to repair the damage–both to the park, and to our reputations as an emerging digitally networked society. There’s now a Facebook group to organize volunteers to help Repair Millenium Park and, a fund where you can donate a couple of coins to help pay for the damage. If you believe in the power of networked communities, add a dollar to help turn this story around.
