I think it would be more informative to ask people to take one specific online test, now, and report their score. With everyone taking the same test, even if it's miscalibrated, people could at least see how they compare to other LWers. Asking people to remember a score they were given years ago is just going to produce a ridiculous amount of bias.
Don't forget those of us who aren't native English speakers. Didn't try it again recently, but I used to have a 5-10 points difference between an IQ test in French (my native language) and English. Word-related questions are of course harder, but even for the rest, I'm not sure if it's because it took me longer to process the English (while the IQ is time-limited), or just that decoding a non-native language use more brain power (leaving less for solving the problem). But anyway, I score better in my native language than in English, and I answered with my score in native.
The final straw was noticing a comment referring to "the most recent survey I know of" and realizing it was from May 2009. I think it is well past time for another survey, so here is one now.

I've tried to keep the structure of the last survey intact so it will be easy to compare results and see changes over time, but there were a few problems with the last survey that required changes, and a few questions from the last survey that just didn't apply as much anymore (how many people have strong feelings on Three Worlds Collide these days?)
Please try to give serious answers that are easy to process by computer (see the introduction). And please let me know as soon as possible if there are any security problems (people other than me who can access the data) or any absolutely awful questions.
I will probably run the survey for about a month unless new people stop responding well before that. Like the last survey, I'll try to calculate some results myself and release the raw data (minus the people who want to keep theirs private) for anyone else who wants to examine it.
Like the last survey, if you take it and post that you took it here, I will upvote you, and I hope other people will upvote you too.
