Bitcoins have come to Oakland.
There are billboards in Temescal (picture) and on Grand Avenue. The billboards are being placed all over the Bay Area by Arise Bitcoin. Here's an article about them.
There was a bitcoin fundraiser for 2014 Oakland Mayoral candidate Bryan Parker.
There's a "bitcoin mining operation" in the Oakland Hills.
Feed Open Source is an open source funding platform using bitcoin with known ties to Oakland. I also hear bitcoin talk pretty often at Sudo Room.
What else?
