I love what CouchSurfing offers to traveler community and we should find ways to support them in long run, to keep them going, though spiced to give HoloChain flavor.
Though on the side note if anyone is considering similar ideas that resonate with CouchSurfing or AirBnB or something in between, please include me. I would be more than happy to tag along and help in ideation process.
For Example: Why are we tied down to our house in a particular country? Could there be a serious service or community that gathers around the idea of Family Swap - relocating for 6 months to year to another country another home - living and experiencing a totally different culture - where neighbors help integrate, assist the visitors to feel welcomed, experience their culture and involve in their community efforts, festivals, ceremonies etc.
