Have been tweeting away like a good social media stooge since March 2008, and suddenly Twitter Central starts nudging me to "complete my profile" so my "friends can learn more about me." (Friends is internet code for advertisers.) Seems I left some blanks in the form four years ago: "location" and "bio," feeling amply covered both. It's hard work being a rebel, shaman, internet provocateur, or whatever you feel comfortable calling it. Your little "art" ideas will be remorselessly ground down by the commerce and conformity robots.
