Nobody cares about some signals.
Everyone by now is so accustomed to the simple fact that there's never anything new or unknown at any "unknown signal" or "place of interest" locations that nobody is bothered to look for anything interesting. The gameplay is exceedingly repetitive, monotonous and unoriginal.
And also there's the fact that any news item or community goal does not directly impact game mechanic, gameplay or experience of the player. So why should we bother? Plus it's extremely easy to miss those. I, for one, never know about current community goals, I don't even know where to look for this information in the game.
well the launcher would be the tool to tell you. Also, doesn't galnet ingame tell it? but not sure, haven't checked galnet recently.
