The document discusses the rise of niche blogging and media focused on biking. It notes that single-topic websites have been successful as startups because they can build community without needing to provide context. It also argues that the main problem with local news is that everyone cares a little about many topics, rather than a lot about one topic, which made profitability difficult historically but is addressed by niche media that empowers small but dedicated audiences. Niche media sites focused on biking include social forums, lifestyle blogs, general bike news sites, advocacy news sites, and urbanism news sites.
