content: I'm fine with advertisements, even though I've never found them useful myself. If advertisements were  Useful (Targeted at things I want, especially on sale) Non-intrusive (No flashing. No adobe flash or javascript ads. HTML5 ads with animations are fine. Nothing that covers the screen or pops up)  They would not only be incredibly more effective, but also lose their status as such a large nuisance that programs are made specifically to remove them entirely from your browsing experience.
