Wow, what a simple and powerful idea. Sharing a extra bed that you might have with a fellow blogger visiting from other cities. Extrabed.in is a wiki where you can list your city and as to what you got to offer there. The idea is you offer somebody to stay at your place when they are visiting your city and next time they are in your city, you can stay at their place. You save money and you got to interact with like minded people rather than sitting alone and watching TV in the hotel room.
There is a need for more people to get on their site with a possibility of meeting really cool people.
