I've just been puzzling about the Lounge. The exact same people are still in there, posting the exact same stuff they were when I first joined. Don't they get bored of it?
I think I've figured it out, here's my theory. American BLers on the whole are extremely boring and dull. A bit like Americans in real life. Amongst the masses of boring and dull there are the cavalier few who consider themselves witty, or funny, or interesting. Please note 'consider themselves'; the bar is not high.
So this minority group gathers and puddles in the Lounge, and due to a complete lack of atmosphere, no evaporation takes place. So still they all are 5 years later, posting the same memes, and the same posts, and the same hilarious comments and the same hilarious responses. Delighting in and marvelling at each others rapier wit. Its quite sweet really.
