GPS Study for Hiking Blogs

I do quite a bit of backcountry hiking, and occasionally take along a GPS. Notably, the GPS is ill-designed for the things I actually want to do with it. It made me think about whether it would be interesting to do a study of GPS as used by skiers and hikers, not so much out in the field, but how they would like to use it in terms of generating trips / blogs / location-dependent photos, etc. Somewhat narrow, but may be interesting. Some obvious uses are to document trips, and to post them.

For example, my pet peeves with my GPS.

in the field, its hard for me to annotate a description onto a particular spot, although its easy to save a waypoint
my camera and GPS are separate (although personally I am not big on location-based photography), but it may be nice to link photos to a map
its tedious to create a blog entry (I don't bother), e.g., a map, a description, photos, etc. While all the bits are produced by my unit, creating a blog-type entry that I can easily edit is hard.

Outcomes:

a study of a new social use of GPS via blogging / hiking web sites
some recommendations on designing GPS units and on-screen software so they are suitable for amateur trip recording.
