The fine art of stating the obvious....

Most sites are not big enough, traffic-wise, to generate significant revenue. Assuming a mid-size blog gets about 1,000 unique visitors per day, and an ad delivers 1 cent per impression, you're only talking ten dollars a day. If you're instead getting 25 cents for a click-through, you would need 4 percent of your visitors to click on an ad to achieve that same ten bucks. And advertising click through rates are usually in the low tenths of a percent, let alone full percents, so most numbers would actually be much less than this. Even if you move any of the dials up by a factor of ten, you're not talking about life-changing money.

But Web services like Facebook, Digg, or TechMeme are in themselves destination sites that are sticky, pulling in consistent viewers and repeat visits, made even better when these sites have personal, demographic information that helps tailor ads and messaging. These Web services are adding real value to the Web by changing the way we interact and communicate. Bloggers, myself included, are not. We are more like consumers than producers in this case, and the last time I checked, consumers pay, they don't get paid, no matter how excited we might be about a product.
