Indeed, discovering all the goodness people have built on top of OSM is not particularly easy, especially for non-technical users. A long list of OSM based services is available in the OSM wiki [0].
A useful collection of links for non-technical users is hidden inside the streetcomplete app [1] (which itself is one of the most remarkable apps built on top of OSM). To find it, open the "my profile" view and then the "bookmark" icon). The list is unlocked gradually using some gamification (as a reward for completing quests). The complete list (for the impatient :-) is available here [2]
