Mostly I play as a lone wolf, but strikes put you with two other players so theres that. While i played the beta i always had a goal wether it was just grinding for something or just completing miscellaneous (did i even spell that right?) missions. I would see another player and would think, great, someone else to take some kills from me. Not often did I try to talk to them or dance around them. Im just a lone wolf. I guess its the one thing I regret not doing in the beta and alpha, not playing with anyone else outside of strikes and crucible. Once the game is out i wont be forced to focus on my small tasks in the short time we had to play so i most likely will try to get along with other guardians i meet through explore when im not so busy with a mission to be completed.
