As Airbnb obviously want to keep the introduced change in sorting of feedback (hosts have been complaining for so long now) then a suitable solution for guests would be to provide them with a 'sort by date' option at the top of the feedback. Really, who wants to know old feedback when looking at a property, and it is a bit insulting to think they would mostly be interested in feedback made by fellow countrymen. Also at the moment there is no way for a guest to know that the host has regular guests, when the last feedback displayed could be months old.
