When you have kids you can just put the Terrabytes of music you've accumulated over your lifetime right on to their computer. I mean, think about how much fun it is when you discover a few of your parents records - now just multiply that by 1000! just think - the mp3s you ripped or got from napster as a college freshmen could be passed down digitally to your children and to your grandchildren!!
Now think about that same phenomenon happening with all your DIVX movies and all your episodes of Sealab 2021!! And even better, all your personal Digital pictures. I have over 7000 digital pictures taken over the last 6 years of my life. just imagine how cool it would be if by the time you're 60 you could just pass 100,000 digital photos chronicalling your life to your grandchildren?
I guess for me this is especially exciting considering I don't have even the slightest idea what my paternal grandparents looked like (actually, I don't even know what their names were... hrm...) nor do I really know what was going on in my father's life before I was born. but just think if you could just hand over a photo library of every party and every vacation and every cat you've ever had in your life? I mean, even just in the last 6 years you can significant changes in me and my friends. just imagine in 10 years? wuuu. exciting!
plus imagine being able to just put 20 terabytes of southpark, simpsons, family guy and futurama episodes on to your kids computer. I mean, I would have totally enjoyed that!
plus What if I keep this journal for the rest of my life? then my gradkids could have this super cool journal of my whole life! and their parent's whole life. that would be super cool.
I think the historical significance of bloggin is super cool. I mean, just think about how amazing anne franks' diary was when they discovered it. I think that historians in 50 years are gonna be writting books and plays about the amazingness of "the diary of mega man"
