I don't know. The specific examples are obviously adapted to current-day webdesign styles. But the general guidelines and direction to take on improving details on today's webdesign styles seem to me exactly the same as webdesign 10 years ago (weight, colour, shading, hierarchy, white/spacing, balance, affordance, it's all there). There's only maybe one or two examples that wouldn't be applicable 10 years ago because we didn't use those stylistic elements. Like putting a coloured line at the top of your page for a splash of colour. That wasn't part of the shiny-button web2.0 style back then :) However, I remember reading design-tips back then and "add a splash of colour" was definitely part of the tips, just used a different trick to implement it that fit the design of the era better (use coloured headings, for instance).
