If the route gets the label "Recommended" the following takes place:
SEARCH: The default search setting is to show ONLY routes that are "Recommended". As a user you can change these default-settings and drop the score-limit below 3 (read here more about the search options)
STAMP: On the RoutePage, the route gets a clear "stamp" at the top indicating the route is "Recommended"
HOME-PAGE: The route gets much more exposure (e.g. you "Recommended" route is put in the spotlight on regula basis on the Home-page)
