Ironically I was one of the first ones too but never really participated since I didn’t think the site would actually have lasting power. Never ask me to pick the winning horse.
Same thing with Bitcoin. I knew about it from the first day, but never mined any since it was such a dumb idea. Face palm.
Don't be too hard on yourself, it's next to impossible to guess which things are going to be transformational and which aren't. Look at some of the early early emails from Linus Torvalds on linux. In his mind the original linux kernel was just a cool toy that other devs could play around with. He invented linux and even he never saw it becoming the OS of practically the entire internet.
