How Do Bloggers Make Money?

From Slate:

Last week, the blog search engine Technorati released its 2008 State of the Blogosphere report with the slightly menacing promise to “deliver even deeper insights into the blogging mind.” Bloggers create 900,000 blog posts a day worldwide, and some of them are actually making money. Blogs with 100,000 or more unique visitors a month earn an average of $75,000 annually—though that figure is skewed by the small percentage of blogs that make more than $200,000 a year. The estimates from a 2007 Business Week article are older but juicier: The LOLcat empire rakes in $5,600 per month; Overheard in New York gets $8,100 per month; and Perez Hilton, gossip king, scoops up $111,000 per month.

Either that $75K figure is seriously exaggerated or I’m doing something very, very wrong.

The world’s 23 toughest math questions

From NetworkWorld.com:

Those wacky folks at he the Defense Advanced Research Projects Agency have put out a research request it calls Mathematical Challenges, that has the mighty goal of “dramatically revolutionizing mathematics and thereby strengthening DoD’s scientific and technological capabilities.”

The challenges are in fact 23 questions that if answered, would offer a high potential for major mathematical breakthroughs, DARPA said. So if you have ever wanted to settle the Riemann Hypothesis, which I won’t begin to describe but it is one of the great unanswered questions in math history, experts say. Or perhaps you’ve always had a theory about Dark Energy, which in a nutshell holds that the universe is ever-expanding, this may be your calling.

DARPA perhaps obviously states research grants will be awarded individually but doesn’t say how much they’d be worth. The agency does say you’d need to submit your research plan by Sept. 29, 2009.

So if you’re game, take your pick of the following questions and have at it.
