Started by a group of bloggers in 2005, and then organized by ADCT since 2006, BoF(Birds of a Feather), aka Taiwan Youth Blog Festival, has become the major Web 2.0 event in Taiwan. This year, because of Typhoon Morakot that wreaked havoc in August 2009 in southeren Taiwan, BoF 2009 on 9/27 focuses on how online community, as a part of local society, should have leverage in the offline world under the theme “Clean UP!”. Besides damage mitigation, this year BoF also divide sessions for microblogging, blogger economy and family bloggers, observing how different trends and innovations change the landscape in the blogosphere.
