I think we should classify all posts that people do while at home off-topic. We are a travel site and users should be true to the topic at hand. Why do I think this would be a good idea?

• We have too often people who make assumptions on trips without researching. If we force people to at least travel somewhere when posting, they get into the proper frame of mind and will therefore ask smarter questions
• We have too many theoretical questions that are just there to give us work in answering which however have no practical application. If we force people to ask only what they need right now, we make sure this does not happen.

How to enforce this?

• If people want to ask something about Paris, they have to prove a) that they do not live there (i.e. show some proof of residence of another location) and b) that they are actually in Paris. If they ask what the cheapest flight is, they have to prove that they are actually at the airport. For this, we need to implement a new SE-Selfie app that automatcially posts the selfie into the question.

It would significantly lower the the amount of work the regular users will have to do in answering the questions and much more meaningful questions would be possible, too.
