Some interesting pricing stats in iPhone appsDecember 3

Ben Lorica at O'Reilly has updated his analysis of pricing trends in iPhone apps. Although it doesn't include the actual sales figures for the apps, it does look at the number of apps in each price category and the top 100 most popular.

Some highlights:

During the last week of November, there were close to 9,800 unique apps, 22% of which were free:

The average price of a Top 100 paid app continued to decline, falling to a little over $2.60 in the last week of November:

 

In both the Social Networking and News categories, the Free outnumber the Paid apps. (Social Networking apps tend to be apps designed to help users access social web sites from their iPhone, while News apps do the same for news/media sites.):

Living life without moneyDecember 3

A WSJ video about an economics graduate in the UK who's going to go a year without using money. It sounds like a step up from dumpster diving for food to me, but perhaps he's got a more subtle plan than this video reveals.

The miraculous power of scaleNovember 17

In this talk at UC Berkeley, Google's Sergey Brin confesses (at minute 1:27) that he thought Wikipedia couldn't work. Most people wouldn't contribute, he rightly assumed, and it would never reach critical mass.

He was in good company. In the classic "free rider" problem, you imagine an elementary school class with 20 students. If only two parents (10%) agree to volunteer to  help out as room parents and drive on field trips, the whole system breaks down: there aren't enough helpers and the two parents get angry at the others for not joining in. And that's exactly what Brin assumed would happen with Wikipedia.

But he was wrong, he says, because he--even he!--had underestimated the way scale can change the game. Sure, the experts say only 1% of Wikipedia's users actually contribute to making it better. Indeed, if you do the math, it's even worse than that: probably closer to 0.01% (today, Wikipedia has 75,000 active contributors out of 684 million visitors). But that 0.01% have created 10 million articles.

Most people don't contribute, just as Brin had feared, but it doesn't matter because the tiny fraction that do are a tiny fraction of an absolutely whopping number.

The lesson is that more is different. The Internet, by giving everybody access to a market of hundreds of millions of people, can work at participation rates that

Does the Long Tail create bigger hits or smaller ones?November 16

Over the past few weeks there has been a flurry of reappraisals of the Long Tail, most of which center around the question of whether it creates bigger blockbusters or smaller ones (more concentrated markets or less concentrated ones). 

My predictions have always been that massive increase in variety plus massive improvements in "filters" (tools to make it easier to find new stuff that's right for you) would tend to reduce the blockbuster effect and redistribute attention over a wider range. And, indeed, that's what the data I cited in my book showed, where online markets of books, DVDs and music saw between 20% and 40% of the demand shift to products not available in traditional bricks and mortar stores. 

But there were clearly exceptions to this. One of the main ones was the irony that there was a very short Head of Long Tail aggregators: Amazon, iTunes, Google and their kin dominate their markets to a blockbuster-like degree. 

I blamed this on a still-young market and assumed that even aggregators would fall victim to the flight from one-size-fits-all someday. But

Freemium math: what's the right conversion percentage?November 14

In my original Wired article on Free, I described Freemium as the opposite of the traditional free sample: instead of giving away 1% of your product to sell 99%, you give away 99% of your product to sell `1%. The reason this makes sense is that for digital products, where the marginal cost is close to zero, the 99% cost you little and allow you to reach a huge market. So the 1% you convert, is 1% of a big number.

But that was just a hypothetical percentage split, to make a point. In the real world, what's the right balance? The answer varies from market to market, but some of the best data is in the games world.

In online free-to-play games, companies aim to structure their costs so they can break even if as little as 5-10% of the users pay. Anything above that is profit. Which is why these numbers from Nabeel Hyatt are so impressive:

• Club Penguin: 25% monthly uniques pay, $5/mo per paying user 
• Habbo: 10% monthly players pay, $10.30/mo per paying user 
• Runescape: 16.6% monthly uniques pay, $5/mo per paying user 
• Puzzle Pirates: 22% monthly players pay, $7.95/mo per paying user

As the blog notes, that compares very well to the 2% of the casual downloadable game market that pays, or a 3-5% that a lot of "penny gap" free trial web startups get. Estima
