Here's one attempt to pin down what's driving it - from the HobbyPrincess blog.
On the Redefining Craft blog, Dennis Stevens poses an important question:
Where is the definition that addresses craft with respect to the flurry of creativity that we are currently seeing within the DIY community?
Certainly this is craft or crafting, just not craft as we commonly know it. It is slightly reminiscent of the 1970’s craft movement, but this a remix; it is witty and it is often nostalgically ironic and it offers biting sarcasm with regard to the presumed role of domestic creativity within our culture. However, a common definition remains elusive.
A number of bloggers are addressing this field and their taglines are descriptive of the common themes among DIY craft practitioners, i.e.:
Extreme Craft: Compendium of craft masquerading as art, art masquerading as craft, and craft extending its middle finger
Craftster: No tea cozys without irony
SuperNaturale: Celebrates ingenuity, creativity and the handmade
Craftivism: Documenting the crafty life, stitch by political stitch
WhipUp: Handcraft in hectic world
