This is one of those games where streams won't bother me. There's an unfathomable amount of things to discover in this game, that I won't mind watching another player explore a portion of the universe I will never set foot in during my journeys.
I plan on livestreaming my adventures as well when the game releases, and posting my screens in the photo thread (I already have the photo thread OP created, I'm just waiting for the 8th).
I don't care about seeing the other alien factions in the game, or even a bit of lore. I remember Sean saying that he is hoping that a community will be built up around this game, where players are cataloging and uploading and sharing their discoveries with other players. Things like recipes, resource tips, ship guides, etc, etc. Things beyond just the atlas. I find having hundreds of streams of people playing No Man's Sky isn't going to diminish my own exploration of the game. I can't fault people for wanting to go in as blind as possible, however, so I'll personally respect spoiler rules, but the photo thread is going to be a little bit looser in that regard. Share what you find is really my only big rule, but I do have some spoiler guidelines in there anyway.
Watching streams is probably going to be the only thing that gets me through the day at work. It sucks that I probably won't get NMS until the evening on the 9th (although I admit I'm tempted to buy it digitally for my wife and play on her PS4 until my copy comes in, but I'm a patient guy), and I'll only be able to play for a little bit before I have to go to bed and work the next morning. All I know is Friday August 12th is going to be a long night once I get home from work. I'll probably fall asleep with the controller in my hand. I'm ready to get lost in this vast universe.
