682 is the most referenced scp.
Hopefully, newbies are spending a lot of time reading the already succesful articles and tales. Which is going to expose them to a lot of repetitions of "let's try it on 682" or "make sure 682 never gets near this." Especially when ther read the older stuff. I don't think it's surprising at all that we get a lot of first attempts with 682 on the brain.
Just thought of something, how many articles do you think you could refer to by number and most members wouldn't have to go look it up to see what you were talking about? 682, obviously. 173, almost certainly. 55, maybe. I don't think there are any others well-known enough that you could count on it.
