This is pretty common OP, I think I played the game in Open for about 3 weeks before I saw another player. It's the main reason some of the community wants Solo/PG revisited, the game is a straight up ghost town majority of the time.
If you want some player interaction, head to a Community Goal, you'll find plenty of players there (depending on location/time of day). Once you start doing engineering, you'll also run into a lot more players around engineer outposts. If you're a combat pilot, Kremainn is a common hangout for bounty hunters (close to start, high security, good selection of RES Nodes, station has lots of modules). I was there about a week ago and saw half a dozen hollow triangles in the station each docking.
