Is there some kind of unknown meta - to me at least - of why people not posting the system/planet name/coords with their screenshots, so that others could also find them?
It could be that you don't get Paid for discoveries while out in the Deep, but have to wait till you get home. I've been out about 4 months on this trip and have found a lot of things. Now whether someone would try to travel out, scan/map/walk on a planet someone else did, and try to come back is rather far fetched.
Then, too. It's very rare that someone would travel this far out to revisit a planet, so never really make notes of where they found anything. At least I don't. But then I'm lazy. :]
