Also, here's a quote I had saved on a sticky note on my computer. I think it's especially applicable for blogging:
"Have we all become too hip? Have we overdosed on irony within a heavily mediated environment where everything is experienced from an ironic because meditated distance? Is communication now more or less an entertainment, a presentation of a public self with any number of knowing asides to an imaginary, clued-in audience?" (Slayden)
I wish I could know more about it's origins than simply "Slayden," but that's all I have for now.
