Hi, I'm Aaron Parecki, co-founder of IndieWebCamp. I maintain oauth.net, write and consult about OAuth, and am the editor of several W3C specifications. I help people learn about video production and livestreaming.

I've been tracking my location since 2008 and I wrote 100 songs in 100 days. I've spoken at conferences around the world about owning your data, OAuth, quantified self, and explained why R is a vowel. Read more.
