Interesting finds, random goodness, and pointless bits & pieces that don't fit anywhere else

Filed undercoffee

I'm a freelance writer, a human rights and environmental activist, and a social justice advocate. I'm also a social media butterfly and an information addict. Oh yeah, and I like bicycles and bouldering. A lot.
