The reason that we have vibrant startup driven innovation is because the Internet is open by nature. Anyone can participate without asking permission and anyone can compete with anyone else at every layer of the stack. This DNA of open and free competition (except for the occasional semi-monopoly) is what allows startups like Google to come in and displace incumbents. If it weren't for the Internet, I'm positive that the telcos would have determined that it was the most efficient that THEY design and operate the "online directories"...Link
In 2006 in Japan, mobile advertising was only $330M vs Content (Ringtones, Song-tones, Games) at $2.2B and Commerce at $4.7B. (http://www.johotsusintokei.soumu.go.jp/whitepaper/eng/WP2007/2007-index.html) Although all of us are experimenting with advertising and advertising is increasing on mobile, the overwhelming percentage of money spent on mobile devices goes to paying for and the collection of payments for a small number of not so innovative products from a small number of providers.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
