Facebook Growth Regions and Gender SplitYesterday

Since we began tracking Facebook demographics in late May, weekly growth has held steady, usually in the low single-digits on a percentage basis. More importantly, it's fair to say that the company has successfully expanded overseas. With close to 128M users, the share of U.S. users is down to around 30% from 35% in late May:

Over the last three months, Facebook has added members across all regions, with the strongest growth coming from Europe, South America, and the Middle East/North Africa:

In Europe, growth has been especially impressive in Italy and Spain. I'm not sure when the Italian translation of Facebook launched, but soon after, Italians s










Getting OpenID Into the BrowserDecember 2

Google Chrome did a smart thing: Less. They unified the search box and address bar, since that's what people do anyway. That gives us back precious pixels for the only thing that's as important to an average web user as where they're going: Who they are. Identity belongs in the browser. Don't just believe me, just this week ReadWriteWeb talks about The End of Online Anonymity and TechCrunch on how Facebook Connect is the Biggest Battle Yet For Social Networks: You, Your Identity And Your Data On The Open Web.

As Web 2.0 took root, the ability to login to a site, store preferences and build a profile became ubiquitous. Beyond reading news or blogs, it's fairly rare that you're on a site where you're either not logged in or don't have the ability to login. The downside is that just about every site requires you to create a new account and have cookies to keep you logged in. Thus when your cookie disappears, you have to login again. Maybe your browser's password manager eases this pain, but there are plenty of people that would be in a world of hurt if their browser every forgot all of their passwords (or they use a friend's computer).

If we remove passwords from the equation and instead use OpenID, there's the notion that upon visiting an OpenID enabled site (now numbering more than 25,000 a

iTunes App Store: The First Five MonthsDecember 2

Taking a cue from Raven's recent post announcing the 10,000 iPhone app milestone, I decided to update some charts from earlier posts on the U.S. iTunes app store. First, the weekly growth in the number of apps was slower in November: the number of apps grew less than 10% on a weekly basis for all of November. 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:

Since high-priced top-sellers actually inflate the MEAN price, I created an alternate chart using the median (the decline in the MEDIAN price is even sharper). The corresponding










10,000 iPhone AppsNovember 30

Two services that track the iPhone App Store - AppShopper and 148Apps, announced on Saturday that there have been over 10,000 iPhone applications released on the US App Store. The number of currently available applications is just shy of 10,000 due to discontinued apps and a few that have been pulled by Apple (e.g. trademark disputes, terms of service violations, etc.). AppSherpa believes that it will only be a few more days until there are 10,000 iPhone applications available for sale on the US App Store. Total international App Store numbers are not being tracked by anyone outside of Apple, as far as I can tell.

Quick stats highlights from the first 10,000 iPhone applications:

  • Games are the leading category, accounting for one in four of total applications. This reinforces Apple's recent marketing campaign around games.
  • $0.99 is the most common price point, although one in four applications are free.
  • The most expensive application currently for sale is iRa by Lextech Labs for $899.99. This is video surveillance application that integrates with a number of CCTV systems.
  • The entire iPhone App Store catalog could be purchased for just over $30,000, although there's only room to fit 129 of them on your iPhone or iPod t
Why I Love TwitterNovember 29

If you care what I think, you know that Twitter is just about the best way to learn what I'm paying attention to. I pass along tidbits of O'Reilly news, interesting reading from mailing lists and blogs I follow, and of course, tidbits from the twitterers I'm following. These are all the things I could never find time to put on my blog, but that I spray via email like a firehose at editors, conference planners, and researchers within O'Reilly. A lot of my job is, as we say, "redistributing the future" - following interesting people, and passing on what I learn to others. And twitter is an awesome tool for doing just that.


Like a lot of people, I tried out Twitter early on, but didn't stick to it. Most of the early twitter conversation was personal, and I didn't have time for it. I came back when I noticed that about 5000 people were following my non-existent updates, waiting for me to say something. With that many listeners, I thought I'd better oblige. (There are now close to 16,000.) I soon realized that Twitter has grown up to become a critical business tool, ideal for following the latest news, tracking the ideas and whereabouts of people who will shape the future of technology, and sharing my own thoughts and attention stream.


I thought I should outline here some of the specific things I find so compelling about
