The tyranny of numbers

Jakob Nielsen’s latest column, about the dangers of quantitative studies, is out. In a nutshell, he argues that numbers lie. Misrepresentation of statistical significance, confusing correlation and causality, ignoring covariant variables, over-simplifying analysis, and out and out distortion of the measurements are of course all potential pitfalls in any research, and it’s good to point them out. Of course, I have a copy of How to Lie with Statistics on my bookshelf that made the same point fifty years ago—and made it more entertainingly.

There’s also an interesting connection to Mark Hurst’s column from two weeks ago about the “Page Paradigm.” Nielsen, who has been advocating breadcrumb navigation and other usability features for years, rises like a brook trout to Hurst’s bait that breadcrumbs, unless they help the user fulfill their one purpose in visiting, are useless. He makes cogent points about users who drop into a site from a search engine or other outside links, or who might want to revisit a site, but still I have to wonder whether the timing of that particular discussion is coincidence.

Still, I have to agree with his fundamental point that quant isn’t everything. I was recently in a situation where we had mounds of hard quantitative data—we were, almost literally, drowning in it—but couldn’t solve our fundamental challenge. Had we been able to run a few focus groups, we could have zeroed in on the problem much more effectively.

Online user experiences: does consistency matter?

Via Tomalak’s Realm: Mark Hurst writes on GoodExperience.com about how users interact with websites by discussing something he calls “The Page Paradigm.” He distills the patterns of user interaction with websites to the following rules (paraphrased):



  1. On any given web page, users will either click something that appears to take them closer to the fulfillment of their goal, or click the Back button.
  2. Users don’t care “where” they are in the website—the site structure and secondary navigation is largely irrelevant.
  3. Users only come to a website when they have a goal. If your site helps them fulfill that goal quickly and easily, the user will have a good experience. Nothing else matters.
  4. User interface consistency is not important on the web. Efficiency in helping the user fulfill their goal is.

In practice, he says this means that on each page, you should identify the user’s goals, de-emphasize or remove areas of the page that don’t help the user fulfill that goal, and emphasize links or other elements that help the user find the goal.


It’s hard to argue with his practical recommendations. His rules, though, are open to investigation. Surely site navigation and structure, if consistently defined and executed, plays some purpose in helping users figure out how to accomplish their goal.

What about the right to publish?

Still catching up with my blogging from last week. As reported on BoingBoing, FCC Chairman Michael Powell last week articulated four Internet Freedoms that he believes Americans are entitled to:

  1. Freedom to Access Content. First, consumers should have access to their choice of legal content.
  2. Freedom to Use Applications. Second, consumers should be able to run applications of their choice.
  3. Freedom to Attach Personal Devices. Third, consumers should be permitted to attach any devices they choose to the connection in their homes.
  4. Freedom to Obtain Service Plan Information. Fourth, consumers should receive meaningful information regarding their service plans.

Nowhere in this list is anything that indicates that “consumers” (as Powell meaningfully calls Internet users) could be anything but consumers. The reality is that the Internet has always been, to abuse a phrase, a “World of Ends.” Remember, no one owns it, everyone can use it, anyone can improve it. Including “consumers.”

I want to see a fifth right added here: the freedom to publish. Unfortunately, restrictive ISP service agreements that prohibit running servers, plans to “improve” the Internet to prioritize broadcast traffic over that generated by mere “consumers,” and other restrictions on the “two-way Web” promise to keep this “right” off the list for good.

SmartManila first impressions

To my surprise, SmartManila eventually did download all the content from my site, back to 2000. I was also impressed that while it was downloading the GUI was responsive and I could do other work.

I wasn’t able to post however; the message just posted in my discussion area rather than a news item. Here’s what I wrote:

User interface gripe: Manila only allows one category at a time for news items, but not only does SmartManila not prevent you from selecting multiple categories, you have to if you want your news item to have a category and appear on the home page, since they have inserted “Home Page” as a category.

There is a toggle in the editing pane from WYSIWYG to raw HTML, which is good. However, they uppercased all my lowercase HTML tags. That would be a problem if I were doing XHTML.

Alternate blogging interfaces

SocialDynamix, who make a front end for Radio, now have a beta of a similar product for Manila, code named Smart Manila, that allows you to manage multiple Radio and Manila sites with a single client side UI. Windows only.

Usual start up pains. I’m not sure why, but the tool couldn’t automatically find my XML-RPC gateway from my Manila site address. Once I manually entered the address, by appending /RPC2 to the edit site URL, it was good to go.

Now it’s trying to download every single post I’ve ever done. Since I’ve been blogging daily for almost three years, it’s going to take a LONG time. Later today I’ll try posting something from there.

I also have been playing around with .Text, the .Net-based blogging framework for Windows. Unfortunately the blog isn’t publicly accessible (I’m using it to become one of those embedded behind-the-firewall department-level bloggers), but the framework seems pretty good. But where are the GUI clients? I am really coming to hate editing blogs in a browser. It’s good to have the capability every now and then, but as a daily thing it’s not the best interface in the world.

The keiretsu in full effect

The keiretsu has been a little quiet the past few months. Now with Esta’s blog active again it comes roaring back. Evidence:

  • In Esta’s latest post, she reclaims the b-word for all her sistahs and notes the inherent sexism in curses: “If you call a woman who’s just out-and-out mean ‘bitch,’ why not call mean men ‘bitch’ as well? Or why not call a mean woman ‘asshole’?”
  • George finds an Italian neighborhood place in North Beach which accomplishes the miracle of “good eats at reasonable prices” in the most expensive city on the West Coast.
  • Craig is hooked on politics, and it’s not my fault: “Why don’t I just retype each wonkette entry into my blog?”
  • And Greg has the final word: “This wave of popularity Kerry keeps riding reminds me of a pyramid scheme…I don’t hear a message coming from the Kerry camp; I just hear pleasant, but meaningless, slogans. Pardon my saying so, but we can do better than that.”

Feed similarity: the Also Subscribe To feature

I started to write yesterday about this but decided to wait until something happened. I’m glad I did because the end result was much cooler than I described.

While I was chatting with Dave at the end of his Microsoft talk, two folks came up and asked if there were a way to cut through some of the noise of the RSS ocean based on recommendations. The young woman described it as “people who subscribe to feed X also subscribed to feed y.” Dave first told them that the SDK was open to anyone to code against, then got out his cell phone, called Andrew Grumet, and gave the phone over to Shira who described the idea to him.

I had to leave at that point so I didn’t know how it would turn out. But yesterday Andrew had the first version of Similar Feeds up and running, and Dave pointed to it last night. Here’s my similarity list.

(Incidentally, thanks to all for the comments and pointers over the last couple of days. It’s been helpful hearing other peoples’ perspectives. Shouts out to Tom Harper (subscribed) and Korby Parnell (subscribed).)
