Agreed - a web interface would be very significant boost.
The idea certainly has potential, but first one needs to see the aggregate results (for which phones are way too tiny, and require on to be ... on one's phone)
at first attempt, mapname tries to alias coordinate, so that you can talk about the place without sharing a url. you may say I am at lisasays.1 or last year I have visited lisasays.a or if you are recording a video you may annotate them like subtitles so that your viewers can see what is happening at which location without you providing any map urls
apart from that core feature, I agree that many options can be provided for personalised browsing of this data depending on the client type
