I'm aware of that but some info should not be disclosed, trade routes and prices for example or ships' location, it breaks the immersion of the game, stations can't communicate with eachother cause of the huge distances, having to discover traderoutes and where to buy ships is part of the game, all the other stuff you mentioned should be ingame, there is no way to track your explorations right now
Well, there is still one communication channel that works - ships, more precisely couriers. I see no lore issue with principle that every ship has a computer, which saves some station data after docking (station prices, news, latest gossips, whatever) and then it uploads these data to any other station visited. There is just delay and the ship traffic will dictate how quick these information will spread. So, third party websites providing trade data are not so out of the game and it's lore - as somebody must visit the station to get the data, it works the similar way as described above.
And I ignore in-game lore stuff like Galnet news that is spread instantly in whole universe. It's just simplification of that principle. So if anybody will object that sharing trade/any other data gathered by humans with all it's disadvantages like that these may be outdated and so on is against the lore, then it also should object that stuff like Galnet news, CQC, chat, friend's position on the map and so on shouldn't be there as well. But as was said - it's a game.
