I will echo Deuce's puzzlement in one respect. Most of the fandoms addressed by the survey are what we would consider "geek" fandoms. Ball-jointed dolls is not one I'd ever heard of, and appears at a glance to be an "arts and crafts" fandom that's not particularly geeky, and which I would guess is one of any number of such fandoms. There are quite a few other types of fandoms that have online communities and major events - homebrewers, railfans, gun enthusiasts, historical reenactment, to name a few off the top of my head - that are not addressed by the survey. It would be impractical to do so, so it makes sense to narrow the focus to "geek" fandoms, which is why it seemed strange to include this one odd fandom among the others addressed by the survey.

(Am I making any sense?)
