Apologies for the short diary, but there's something you can do that will cost the people trying to deny marriage rights in California some money. Not much money for each of us, but there are a lot of us.
The yes on 8 people (and I use the word "people" loosely here) just started trying to saturate the web with their ads. Any remotely GLBT relevant web site or page is liable to have one.
If you click on one of those ads, they have to pay the web site owner for it. Not much, probably between ten cents and a dollar, but what the hey. As I said in the intro, there are a lot of us.
Don't just sit there. Click their ads, cost them money.
UPDATE: A google search on "gay marriage" brings up ads from both sides. Don't click the "no" ad unless you're going to donate.
And updated from a comment: Don't repeatedly click on the same ad. That costs them nothing.
