Couchsurfing

The idea is simple yet brilliant: a website where adventurous travelers can search for couches on which to sleep for free, all around the world. My good friend Flint recommended the website to me, and seeing a dire lack of available couches in Shanghai, I made available my own guest bedroom.

If you have a couch and would like to welcome some adventurous tourist to it, by all means go and register! The referral system is well-done, there is not an ounce of sleaze involved, and the website is filled with amazing adventurers and travelers.
