for what to write an article at length if the upvote is just robot @good-karma, which other where?

as long as i join in steemit, i never feel member here socialize, that means they are only selfish, i have tired upvot post others but what reply I get, i post a very useful thing in steemit this is about history, then who is my upvote post useful for you? there is not even a meaningless post out there earning a lot of votes that should not be worth giving upvote
