I was originally pretty open-minded; blockchains are a cool technology, and I like to see people try out-there experiments. But for me this stuff increasingly falls into the same bucket as 3D movies/TV: lots of excitement, cool tech, and a plausible story as to why it could amazing valuable. But in practice, I've seen little value actually demonstrated, so my eyes generally glaze over at this point.
That's part of why I'm curious to hear from people who were excited about the initial vision. Maybe there's a pony in there somewhere?
