I grew up in Australia, and moved to the Bay Area relatively recently.
I'm involved in the Effective Altruism movement. I live in a tiny room so that I can donate more to charity. If that seems dumb, we probably shouldn't date. (Unless you think it seems dumb because you think that I could do more good by spending more money on my living situation so that I can spend more time doing valuable things like doing more programming and networking, in which case we probably should.)
I write songs. Here's one about feminism, pick up artists, and compromise: youtube.com/watch?v=rtrO5w3IsQA.
To quote a now-deleted OkCupid profile, my poly dance card is mostly full at the moment. I have a fiancee and two girlfriends so lovely that I almost always would rather spend marginal romantic time with them. So I don't message people here anymore. Feel free to message me though.
If you're connected to the local music scene, please message me! I really want to start a new band and start seeing good local bands. If you convince me to go to a really good local show which I wouldn't have heard of otherwise, I'll buy your ticket for you. (This doesn't have to be connected to dating me: everyone is eligible for this!)
