Party with a local is an app I haven't used yet. I can definitely see it could be great if you're on vacation and want to meet some local people. Is is sharing economy? I guess if you think of it as people sharing their time with others it could be... Anyway, sometimes they send me notifications, like this one. Haha, "let's go crazy!", was not at all what I felt like at the moment. But I hope someone else had a fun night with Ronnie M.
(For the Swedish readers: på svenska heter appen "Party med en lokal", låter lite stelt kanske :-) )
