So you've decided to make some extra money renting out your apartment on Airbnb, only to realize that you need your own place to stay in the meantime. Don't worry, there's a service for that. Welcome to CISWYWIRMPOA? (Can I Stay with You While I Rent My Place on Airbnb?), a site that lets you arrange to stay with another Airbnb host. This "Airbnb for Airbnb" (their words) is largely ad hoc. Once you pair with someone, it's up to you to decide on payments -- the service suggests splitting your rental revenues or offering to host your new friend, but there aren't any firm rules. Yes, it's a bit absurd, but it shows that Airbnb is now big enough that some hosts want their own support network.
