The GeeksOnAPlane Asia tour kicked off on Monday in Tokyo, with the group of mostly US-based geeks leaving today for Beijing. Former TechCrunch employee Mark Hendrickson already shared his views on the Japanese tech scene from an American perspective, giving me room to summarize (almost) all presentations the GoaP group witnessed in Tokyo (I myself am a Japan-based writer for the TechCrunch network).This means there is a lot of substantial stuff to cover, which is why I will do a two-part posting on the GoaP Tokyo leg (the second piece follows tomorrow). First on the list is Tokyo 2.0, a monthly web industry event that combines networking with a number of presentations and lightning talks (and regularly attracts an audience of about 200 people). This time, a total of four presentations tried to shed light on the question of how language and the web can be interconnected and how this helps in the evolution of the web. Here is a quick summary of all the presentations held during Tokyo 2.0 this Monday.
