On the tenth anniversary of the show, executive producer Joshua Safran revealed that the team had actually been considering Eric van der Woodsen as the secret blogger.
"I always thought it was Eric until the end of season two, and I even guided it that way," he told Vulture. "But when the New York Post revealed it was Eric – and I still don't know how that happened, I think they were just guessing – we realised we couldn't go down that road anymore, so we abandoned him."
To be honest, we kind of get it. Eric *could* be sassy at times...
Next port of call to be good old GG? Nate Archibald. Apparently he seemed like a good choice because he was never sending in life-destroying rumours to the evil blogger. However, the team felt that Dan was the next best choice due to his superior writing ability.
"But in the end, it had to be Dan," Vulture's piece continued, "Because Dan's a writer, observer, and could write in different styles".
So there you go, an explanation as to why it made literally zero sense that Dan was Gossip Girl, the person responsible for saying so many horrible things and destroying the lives of those he loved.
