I notice that most adsense are completely off-topic or unrelated anyway.

Depends on the site and the topic. AdSense works best on special-interest sites. On my own site, targeting has been quite good, overall, and it's been getting even better over the last few months.

Even if it is doing well today, won't the average consumer get tired of reading advertisements at some point.

Why should "ad blindness" be any more of a problem on the Web than it is in newspapers, magazines, radio, or TV?

If the ads are relevant to what users are looking for, they're an asset, not an annoyance--which is why trade and enthusiast magazines are able to attract and retain readers and advertisers month after month, year after year.
