This analysis has two major problems. The first is that housing ads are not a good proxy for total population using Craigslist; different cities tend to have different "velocities of housing" (how many times people move per year). He should have divided housing ads by some other housing supply metric and multiplied by population.

The second is that Craigslist is not the only channel for prostitution. There are high-end channels such as those used by Eliot Spitzer which may be more common in affluent cities, any "brothel"-type establishments that exist, and of course women on the street hollering at cars (the ability to do this may be severely hampered in colder climates).

Depends on the length and frequency of the steps, the length of the leaps and stumbles, and the recovery time between a stumble and the next leap.

When you pay for a real newspaper, you don't get a "no advertisements" option...

Juicy Campus wouldn't have survived in any economy. The site is so repugnant that no legitimate advertiser wanted to be associated with the site.

Official website of the Executive Branch. There can be no official website of the United States unless Congress passed and the President signed a bill to the effect.

Some people's relationship with their employer is so transactional that they will do only the bare minimum to not get fired. This is a good site for them.

> I thought that was what a wiki was for. Once your newspaper for a given day is annotated, how do you search it in the future?

You don't. The asymptotic approach of storage costs to 0 has made some people believe that everything is worth saving.

"in case they fix it"?

I removed the Reply-All button from my Outlook toolbar so that I have to right-click to use it. It definitely reduces the chance of accidentally replying-all.

I always thought it was Harvard which was consistently rated #2 after Yale.

Ask and ye shall receive.

I'm not sure if this is a generally available link; I am using it from a Stanford IP which may have purchased access. The paper is Dale and Krueger, "Estimating the Payoff to Attending a More Selective College: An Application of Selection on Observables and Unobservables."

On the earnings side that is hard to do since so much cost is shared between the retail and web services side, with not a very clear way to allocate it out between the businesses.

mostly the second. A study showed that people who get into Harvard/Yale/Princeton and instead go to state school make almost as much money as they would have otherwise.

Not really. Further shrinking of that board is constrained by the number of I/O pins required, whose size cannot shrink because of the limitations of human solderers.

Maybe a mentally retarded person stole his girlfriend :D

there's mild email-based criticism, and then there's "Your wife's name is XXXX and she works at ______. Shut down your site or else."

Perhaps as the economy goes down the toilet, people shift their entertainment dollars to Netflix as it is one of the cheapest forms of entertainment available. I wonder if Netflix and Walmart are positively correlated :)

Huh? Not only did my apartment have less space than what 3 people would take up at a coffee shop, that $45 didn't cover coffee, electricity, labor, marketing, profit margin, ...

I think the best solution is to have each receipt carry a bar code for a certain amount of minutes of Internet based on the price of the bill, that way people have to keep buying food or get out. Frequent customers can have their credit card linked to their MAC address.

$20 can't cover the cost of that in many markets (NYC/Bay Area/Boston/etc.) The rent on my tiny studio apartment in Manhattan was $45 a day.

Why is your first response to seeing an unlikely achievement to assume that it's not true?

The "5 whys" don't need to be exactly 5; it's just the name for the process of getting to the root cause of a problem.

You don't have to pick just one. On one of my sites I have tables for the navigation elements and CSS for the content elements. Use what works for you.

Well, IKEA probably buys 14,0...0 feet of aluminum tube a year, and their volume allows them to take lower margins than your local metal place, so it makes perfect sense, really.

I haven't herad of that phrase, but that is how FedEx operated for the first several years of its existence. FedEx a package from Boston to Cambridge and it would go through Memphis.

It's why I keep my old vinyl even though I've downloaded the albums on FLAC. The old album art is incredibly detailed at 12x12 inches and an album cover like "Blue," a patchouli-infused sleeve ("Like a Prayer"), or a working zipper to Mick Jagger's leather pants ("Sticky Fingers") are all fun parts of the experience of owning a historical artifact.

What about having it actually correlated to progress?

"The business works," said Mr. Peterson, owner of the East Lansing Horse and Carriage company in 1891. "Why should I change what works?"

Greenspun goes by "philg"

Bigger and smaller computers are a good thing, opening up new types of interactions that are not possible with a 17-22" inch monitor, a 95-105 key keyboard, and a mouse.

Paul - you assert that the economy is less controlled by the biggest companies than it was 50 years ago. Is this supported by data? I would be curious to see what % of total GDP is booked by the top 1% of companies in 1950 and in 2000.
