Obsolete Skills

I just came across this and felt like I needed to write this review now, that's how excited I was about this website. This is like a wiki for all skills that are now obsolete. This includes: eating from a trencher, dueling with swords, riding a rope tow, playing marbles, FORTRAN programming (though the logic is still good, it says), etc.

Each entry includes: the field under which the skill falls, the time the skill went obsolete (some are in the future, for example, driving a car is predicted to become obsolete in about 50 years time), what replaced it, knowledge assumed and when it was useful.

Seriously, this could take up the next 6 hours of my life. I hope the internet doesn't become obsolete for at least another 60 years. I mean, this is kind of brilliant.
