Hi!
Okay, I will try to do at least a little bit of prospecting.
There is just one more thing that came to mind. Looking at the map archive, it seems to me that points of interest can be added by anyone, not only the original uploader. If that is the case, I think using the map archive would be a good way to encourage people to share the interesting sites they have found.
Of course, it is different from the display in the game when you select your site, but it should still give a general direction.
The thing is, I saw the worlds shown in the wiki, and each of them has listed just a single location. But odds are that there are many, many interesting locales on each, also depending on how you define interesting. Thus, I think it would be interesting if more than just one site could be listed with each region, and I think the map archive's point of interest feature could just be the tool for that.
Currently, I have started an experimental fortress in a normal area (2x2) which does not have any neighbors except for dwarves, even though it is continental.
Anyhow, it will take a little while because I will try to do at least a little bit of scouting first (I had hoped for greater interest so that chances would have been high for others to experiment with the worlds, removing the necessity of my prospecting).
