Ask HN: How much do you make from Adsense?

I know we usually like to talk about SaaS and mobile apps here on HN but I'm sure there's a number of folks earning serious amount of cash from Adsense.

You don't have to share the details if you don't want to but it would be great if some of you could give us some insight into how much you're earning and maybe even the verticals you're involved in.
