Tee hee! The above link has a whole load of skills which were 'essential'... and which are now dustbin fodder for most people. Yeah, it's a bit geeky... okay... a lot geeky... but kinda funny too (even if I can still do shorthand despite it being obselete... snark!!)
Wonder what we're doing right now which will be obselete in 10 / 20 years time? Or even, given today's pace of change... next year? Toshiba HD DVD anyone...?
