This sounds like a good idea and vaguely similar to my intentions for
Freemap started out as a project to map the footpaths of the UK using GPS
tracks, and store them in a central database. Now, the idea is to store
Freemap tracks in OSM and to focus Freemap itself on being a
walking-orientated website which uses OSM maps (using a local copy of the
database) and allows the user to overlay, on the OSM maps, the locations
of interesting views, obstructions (bogs, barbed wire, nettles, mad cows,
etc) for others to view, as well as instructions at points where it's easy
to get lost.
Other plans I have for Freemap, which is rather like your idea, is to
allow users to contribute suggested walks, these could be GPX files or
could even be done through the user tracing the walk route on the OSM map.

osmeditor2 will do this. I have two approaches to recording extra
Firstly, when I pass a pub, viewpoint etc, I record it as a waypoint.
osmeditor2 will then upload waypoints direct to the OSM server; it also
allows the user to set the waypoint type (pub, village etc). They will be
converted to nodes on OSM.
A second approach is for users to record things like interesting views,
obstructions, points where it's easy to get lost, etc, later on. These
sorts of things could come with a possibly lengthy text description, and
may be recorded by people without a GPS (e.g. people could click on an
existing map and estimate the position of a good view) so are perhaps more
suited to an AJAX-style web interface than osmeditor2. My approach here
would be to allow the user to click on the map and then enter relevant
information about the feature. If it was a photo they could upload it.
Implementing these sort of features could benefit Freemap, your site and
OSM as a whole.
