If someone today were to identify a consumer products bubble like the Beanie Baby craze or baseball card bubble of the 90s, what would be the best way to capitalize on it. I posited this to my economist friend and he suggested something ancillary like conferences, a publication, or website. I agreed but it'd have to guarantee me a very substantial return for me to go through the work of say putting together a national Beanie Baby convention, on top of the dread of hosting something that I have no interest in. So I'm curious if Hacker Newsers have any other thoughts on how to capitalize on a situation like this for a large return with less work involved.
