The document discusses creating successful online communities and introduces Open Mic, an online community created for BBC 1Xtra. It explains that online communities should complement, not replace, offline methodologies by understanding both online and offline drivers of participation. Reasons people participate include loving the subject matter, social contact with others, and feeling part of something special - none of which are limited to online spaces. Open Mic encourages participation by uploading relevant content frequently, allowing social contact, giving it a visual identity, and using offline outreach strategies. It features profile pages, freestyle sections, and a hall of fame. BBC 1Xtra benefited from Open Mic by obtaining creative insights, reaching a young audience, and informing its creative expression.
