History of the LR:
Back in the day, there was only one forum. During the early part of the Iraq invasion, the forum began to get almost dominated by political posts (initially pro-war/anti-war, but then increasingly anything left vs. right--economy, ecology, abortion, etc.). Many of the non-political types wanted to only see on-topic posts and started beseeching Dan to remove political/off-topic posts from the forum altogether. So, Dan conducted a "poll" and decided to create a separate forum for the off-topic stuff. Tibbs suggested the name "Lavender Room" and it stuck. Very soon after it was created, Tibbs decided he didn't like it because it wasn't what he envisioned it to be--sort of a Penthouse Forum/Playboy Advisor kind of thing (I gather) where people could get together and engage in "smoove" talk, whatever that is.
FWIW--I trace the beginning of the political left/right stuff on the forum back to a Tom Demerly post "What I am seeing right now..." on the eve of the ground invasion of Iraq.
Also, is it just a coincidence that Customer Jon/Mr. Tibbs/Jon/Just Jon showed up about the same time Seinfeld went off the air?
