in a river, where there is a limited # of fish in any spot and usually way too few spots, keeping quite is most likley a good thing to do, but the saltwater is a big place, usually more fish and sometimes a whole lot harder to figure out the depth, bait, tide or place to be. Sharing good info in the saltwater, most times will not come back to bite you in the rear like telling your favorite little pocket in a steelhead stream. So keep at it.
