  • Dilbert comic strip for 05/04/2009 from the official Dilbert comic strips archive. – Secretary to Pointy Haired Boss: "I live in a rented trailer and all of my money is in my checking account. Your investments are worthless and your mortgage is underwater. My net worth is higher than yours now. I guess promiscuity and a G.E.D. was a pretty good strategy after all." Reminded me of a thought I had earlier this year, that much of Western Civilization is built on valuing delayed gratification, which hasn't worked out so well recently as opposed to immediate consumption in many cases.
  • Without Warning, Twitter Kills StatTweets (Businesses Beware) – ChangeLog – Owner of StatTweets post regarding his network of sports-related Twitter handles being banned. They had several hundred accounts, one for stats for each team. This makes sense for users, given the way Twitter works, but they don't like mass account creation. Interested to see how this sorts out, there seem to be at least a few similar Twitter networks with team/region/topic-specific handles.

  • Obesity and Overweight: Trends: U.S. Obesity Trends 1985-2007 | DNPAO | CDC – During the past 20 years there has been a dramatic increase in obesity in the United States. This slide set illustrates this trend by mapping the increased prevalence of obesity across each of the states. In 2007, only one state (Colorado) had a prevalence of obesity less than 20%. Thirty states had a prevalence equal to or greater than 25%; three of these states (Alabama, Mississippi and Tennessee) had a prevalence of obesity equal to or greater than 30%. The animated map below shows the United States obesity prevalence from 1985 through 2007.
  • Why text messages are limited to 160 characters | Technology | Los Angeles Times – A look back to the beginnings of SMS in 1985 – Would the 160-character maximum be enough space to prove a useful form of communication? Having zero market research, they based their initial assumptions on two "convincing arguments," Hillebrand said. For one, they found that postcards often contained fewer than 150 characters. Second, they analyzed a set of messages sent through Telex, a then-prevalent telegraphy network for business professionals. Despite not having a technical limitation, Hillebrand said, Telex transmissions were usually about the same length as postcards.

  • Raphaël—JavaScript Library – Raphaël is a small JavaScript library that should simplify your work with vector graphics on the web. If you want to create your own specific chart or image crop and rotate widget, for example, you can achieve it simply and easily with this library. Raphaël uses the SVG W3C Recommendation and VML as a base for creating graphics. This means every graphical object you create is also a DOM object, so you can attach JavaScript event handlers or modify them later. Raphaël’s goal is to provide an adapter that will make drawing vector art compatible cross-browser and easy.

  • Skew, The Frontend Engineer’s Misery @ Irrational Exuberance – For mashups and the like, the distinction between a FE engineer and web dev is rather small in terms of technical skills; they are both using the same skillset, they are both interacting with APIs, and so on. However, there are important distinctions between the two: 1. web developers tend to move in small groups or as individuals, whereas fe engineers work in larger groups, 2. web developers tend to design a product on top of an existing backend service (api, etc), while fe engineers are usually working in parallel with the backend being developed.
  • Study: Twitter Audience Does Not Have A Return Policy – Over 60 percent of people who sign up to use the popular (and tremendously discussed) micro-blogging platform do not return to using it the following month, according to new data released by Nielsen Online. In other words, Twitter currently has just a 40 percent retention rate, up from just 30 percent in previous months–indicating an “I don’t get it factor” among new users that is reminiscent of the similarly-over hyped Second Life from a few years ago.

  • Stochastic Models of User-Contributory Web Sites – Tad Hogg, Kristina Lerman 31 Mar 2009 Abstract: We describe a general stochastic processes-based approach to modeling user-contributory web sites, where users create, rate and share content. These models describe aggregate measures of activity and how they arise from simple models of individual users. This approach provides a tractable method to understand user activity on the web site and how this activity depends on web site design choices, especially the choice of what information about other users' behaviors is shown to each user. We illustrate this modeling approach in the context of user-created content on the news rating site Digg.

Why I’m not connected to you on Facebook or LinkedIn (but do follow on Twitter and Friendfeed)


Here are my current informal policies for using Facebook, LinkedIn, Twitter, and Friendfeed.  Short version – Facebook and LinkedIn I use for people I know personally, Twitter and Friendfeed any interesting input is welcome.

Facebook: This has been rapidly going mainstream lately. I had a mostly unused account for a long time, which has become more interesting/active as people I know sign up.  I presently only link to people I know in real life. Facebook is interesting because there are people I haven’t interacted with for years (high school friends etc) as well as people that live next door (literally) and colleagues from past work projects all mixed together, and they all get to eavesdrop and engage in casual/passive interaction. I currently have my Twitter feed linked to update my Facebook status, which means my messages are probably cryptic to about half the readers at any given time.

LinkedIn: I originally only linked to people I worked with and knew very well. I have broadened out the criteria over the years, and at this point I will link to people that I haven’t worked with but have at least actually met and had a conversation with. I basically don’t link to people I don’t know and haven’t met, though. I’d to at least be able to recognize people I’m linked to, and have a clue about what they’re like. So no “LinkedIn Open Networking” for me.

Twitter: I look for interesting (to me) streams, whether or not I know the author. Most of my twitter feed is people I haven’t met in person.  I follow people I know in real life, and also discover people who have commented on something that turned up in a conversation or a search. I don’t auto follow, although I do try to take a look at who’s on my follower list periodically to see if there is someone I should add.  Twitter has also been the most interesting for making new connections with people in real life, as you can get a sense of topic people are thinking about and what they’re more generally like.  I use Twitter for scanning a range of topics, so I’m a little less interested in people with huge follower counts and more interested in people kicking out uncorrelated but interesting ideas and data.  I’m working on tools for scanning and filtering status and sentiment streams, so in theory a bigger source network is better, if you can make effective use of it.

Friendfeed: Sometimes I feel like Friendfeed is the Robert Scoble/Louis Gray channel, but I have seeded it with my Twitter feed and have gradually added people as they are exposed through the “friend of” feature.  I always have the feeling that I’m not making the best use of Friendfeed. I like the conversations that pop up on posted items, but wish for the range of input that comes from the huge user bases on Twitter and Facebook. Then again, maybe not Facebook inputs here, I also enjoy the relative skew towards content from early adopters that persists for now on Friendfeed.

If I know you in real life, feel free to send me a Facebook or LinkedIn request, there have been a lot of people signing up lately and I’ve been enjoying reconnecting with people I haven’t heard from in a while.  If I don’t know you (yet), you’re welcome to follow on Twitter (@hjl) or Friendfeed (hjl).
