DIY is hip, we live in the age of the amateur, the age of Makers - according to at least Tim O'Reilly. And some other people. A good example is Instructables a recent website for makers of all kinds of things. Instructables makes DIY a social object by allowing anyone to upload a step by step DIY recipe and then allowing everyone to comment on the recipes.
Nicely executed and already full of food recipes, wood working recipes and semi professional "how to do surprising thing X with simple household object Y" type instructions. Yes, there is also a LEGO Mindstorms 3D printer (that outputs chocolate).
