Users say they don't like to scroll. As a result, many designers try to keep their web pages short. But a study conducted by UIE showed that users are perfectly willing to scroll. However, they'll only do it if the page gives them strong clues that scrolling will help them find what they’re looking for.
Short pages don’t help users: "One criticism of long web pages is that they hide some information, forcing users to scroll. Short pages may avoid this potential problem by showing more (or all) of an individual page, but the information is still hidden — on other pages."

A follow-up on an analysis of e-commerce sites conducted by the NN/g has shown that over the last 1.5 year, the average compliance with the NN/g Guidelines for E-commerce Sites has increased by 4%.
NN/g also found that non-US e-commerce sites are lagging behind. A sampling of six non-US e-commerce sites followed only 40% of the guidelines – compared to a 49% score for the U.S. sites. Taking the current rate of usability improvements into account, non-US sites are about three years behind the U.S. on usability.
According to Jakob Nielsen the reason for this lag might be that the U.S. has a grater maturity in terms of management’s emphasis on usability and that U.S. websites have a larger customer base and thus more resources for improving usability.

While redesigning Audi's main websites, Razorfish did an extensive test of left navigation vs. right navigation. The results showed that:
- There was no significant difference in completion times between the two navigation types for any task.
- People tended to focus more on the content with a right navigation than with a left navigation.
- Users were apathetic towards the navigation position.
In the light of the study James Kalbach from Razorfish concludes that "Don Norman's concept of affordance - the perceived properties of a thing that determine how it is to be used - seems to be a better predictor of usability than conforming to standards or matching patterns to user expectations. With the Audi site, it is clear what is navigation and what is not. Users can build a pattern of interaction with the site immediately."

Michael Bernard has conducted two studies, which sought to better understand users’ expectations concerning the location of common objects on web sites and e-commerce sites.
Some of the findings show that people expect:
- Links back to the front page to be located top-left of a page
- Internal links to be placed along the left side and external links along the right
- Shopping cart, account and help to be located along the top-right side
- Login to be placed top-left

Michael Bernard & Spring Hull have made two interesting studies on where to place associated links to an online document.
Their findings show that in terms of search accuracy, time and efficiency, there is no significant difference between placing links at the top-left of a document, to the left at the same height as the related content, in the bottom or embedded in the document. However, 50% of the test participants preferred embedded links.
Bernard and Hull have also observed that repeating embedded links in the left side of a document at the same height as the associated content makes searching faster (though not significantly) and is ranked significantly higher by the users than a layout with just embedded links.
Bernard and Hull also examined users’ perceptions of frames, and found that the participants ranked a layout with associated links placed in a left frame significantly higher than a non-framed layout.

In the article "In a world Full of Choice: Simplify", Pamela Parkers refers to an interesting experiment aimed to shed light on how people make decisions. The study showed that having a wide range of choices might have detrimental consequences for human motivation.
The Columbia University study was conducted in order to see if people would be happier to choose among 30 different types of chocolates, or rather select from six different options.
The study showed that people took significantly more time to make decisions when presented with 30 chocolates. They felt that they had too many choices and that the process of making up their mind was difficult and frustrating.
Pamela Parkers advice to the Web marketers is not to overwhelm visitors with choices, as they could be struck by paralysis. "It may, as with the chocolates, actually discourage them from buying."

Louis Rosenfeld has put out a brief survey to learn a little bit about whom Information Architects are trying to promote IA to, what gets in the way, and what might help Information Architects to do a better job.
Some highlights from the survey:
- Hardest part of promoting IA: 27% don't get a chance until their projects are too deep into the design/development process
- What would help: 82% plead for ROI cases, 72% for case studies of successful projects
- Hardest audience: Our clients' decision-makers

Dropdown, fly out and rollover menus are getting more and more common on web-sites. But a study from UIE shows that users have difficulties using these menus:
- The menus doesn't help users decide where to click because critical information is hidden
- Users expect to be taken to a new page when they click a menu item, and stops to re-evaluate the screen, when more information is suddenly available
- Most of these menus require users to use awkward movements to make simple choices
Some of these difficulties are due to the fact that users decide what they are going to click before they move their mouse. They don't "browse" the menus first.
Their studies also showed that sites with visible sub categories did a better job of getting users to the content they sought and to content they didn't previously know existed.
UIE’s advice is that if you are going to use these kinds of menus, do some testing to ensure they are helping your users.

Jack Aaronson form ClickZ has done a little survey of the best and worst 'My' sites (personalized sites that allow people to manage their personal information). The article lists the most popular and unpopular sites.
The responses show that people are very passionate about personalized sites, and speak of them as if they were best friends or worst enemies.
My favourite "my" site is definitely Backflip - a service for storing your favourite URL's - though it's a bit slow and could be more functional.
