I was actually thinking about my Bionicle succession plan today as I was putting my sets into storage (living situation demanded it).
Online resources and networking sites like BioMedia Project, BZP, BS01, The Wall of History, and so many more do such a great job at fostering a sense of Bionicle community and making the complete story accessible for all new fans. I've only recently been really getting back into Bionicle but I've been so encouraged by everything I've seen and everyone I've met online. That isn't even mentioning the incredible fan art I see on multiple sites coming out every single day.
Max Nui, I love your plan on sharing your collection with the next generation! As impressive and diverse as the online resources and communities are, I think most Bionicle fans were drawn in by what it all boils down to: a toy line. I saw a joke once that stated that 99% of the world's Bionicles are controlled by 1% of the world's Lego users, and while those numbers are exaggerated it is certainly true that the majority of Bionicle pieces are by now in the collections of established fans, and thus the responsibility of passing on what many would consider the heart of Bionicle falls on our shoulders. What that looks like will be different for each individual person, but I hope we each get the chance to pass on, in some way, the love of Bionicle to someone in our lives at some point.
Twitter user @ HahaMakesGlass recently gave me the idea to put some of my physical Bionicle books in free little libraries around town in hopes that someone might try and enjoy them for the first time, as all the books/comics/etc. are now so readily available online.
