I read a bunch of websites daily, including Hacker News. You'd think you could get thought that pretty fast, but it takes me hours, especially if I get sucked into the comments.

I'm interested in free culture and getting more free stuff out there, so I do some stuff on Wikipedia / Wikimedia Commons and Project Gutenberg.

Theoretically I could contribute to open source software, but there's no project in particular that motivates me at present.
