There are Websites that encourage answering questions from readers by other readers and some of them probably actually help with answers but they are so "dense" as to be not very usable/popular, even sometimes trying to monetize the process: "which way is it to the Plaza Mayor?" - "I'll tell you for a Euro." would never do in face-to-face solicitations for directions.
What if the process were more nearly global and instantaneous so that from your mobile device you could get help for just about anything from whoever participated in the "global help desk" network?
In particular getting tourist information (skip the hotel/restaurant ads, please) from someone in Myanmar about the Plazas of Madrid, etc. might be interesting because anybody, anywhere might: have the info; speak your language; enjoy sharing.
Most mobile smart phones have in effect the means of doing this and when they are as cheap/effective as Skype it will be feasible.
