The SDMB has been name checked- page 166.
On that page, Randall Munroe in his hugely entertaining book “What If? 2” mentions the SDMB -
“What is the density of cocaine? I spent a while reading though a wonderfully earnest and citation-filled discussion of this question on the Straight Dope Message Board where several people tried to get to the bottom of this question…”
That might bring in a reader or two.
Oh, and buy the book. 
I think this is the thread:
There’s also this:
Good searching there! 
Heh…….
IIRC he registered here as XKCD but was banned. Does that scan?
Small chuckle at the poster in that cocaine volume thread who said
Pun presumably not intended.
There is a user named xkcd that appears to have been quickly banned. In the few minutes I looked, I didn’t see an ATMB thread mentioning a reason. But then trying to search this board for mentions of a user named xkcd brings up a lot of erroneous results.
Eh it’s probably for the best. We don’t want any troublemakers like Randall Munroe around here.
Quick bans suggest that it was a spammer. I could see someone borrowing the name for cred. I could also see it being a set of random four letters tried by a bot.
I doubt it was Randal Munroe himself. He’s too computer literate to have done something that would make him look like a spammer.
I had just finished the book and popped in to say, “Hey! The SDMB has some serious street cred now!” but I see that I’d been ninja’d by 106 days.
Tripler
I need to read faster. 
Elsewhere in that book he alludes to a message board thread about how much blood a human can drink without puking, but doesn’t mention which board. I think that might have been us, too.
