This week's Carnival of the Mobilists is at Vision Mobile where Andreas Constantinou has assembled a great collection of blog posts and articles covering the varied mobile scene. This edition features a good Mobile Web Congress wrap up and some excellent think pieces on topics including the mythical mobile "youth" market, mobile's role in education, social networks and viral marketing. Post of the week honors go to Tomi Ahonen for his extensive analysis on which countries are ahead in mobile telecom. Hint, in spite of what CTIA claims, the US is not one of them. Congratulations Tomi.
