I don't think there is any data that would be valid to share in
pointshare exchange that wouldn't also be valid to share in
OpenStreetMap. There are probably things in OpenStreetMap that aren't
useful to Loadstone users, but filtering those things out is not a problem.

If I upload points I find to PointShare, then I reach loadstone users.
If up upload them to OSM, I reach a much wider audience, hopefully
including all LoadStone users. PointShare could be useful as a
repository of external datasets that are useful but not compatible with
OSM's license.

For copying data from PointShare to OSM, you must agree to share the
data under CC-by-sa. Details of what that means are here:
http://creativecommons.org/licenses/by-sa/2.0/

They are planning to move to a different license that is more
appropriate for large databases of information, rather than individual
works, but that is still in progress.
