would like to see a climate change feature. karma points like on reddit instead of references for travelers to long to read anyway on your smartphone. example points for transportation. airplanes are minus 10 points and bicycles +10 and trains are minus 2 points and hitchhiking +2 and long and hot showers in my house minus 5 points points for safety of course and eating meat is minus 10 points and vegan +10 and points for jokes or boring behavior and not show up or cancel last minute is minus 50 points and decides about your ranking in the search results or if hosts can see your public trip,very easy to make algorithms for that and buttons on the profile with a profile views counter because if nobody views your profile you have to work on your karma..
