When I looked at my iGoogle page today I found a short description under each item. Unfortunately that made the paper longer than one screen so I couln’t view all my items w/o scrolling — very inconvenient. Even worse, there was no immediately clear way to restore the original layout. I tried to click on the small arrow in each block to edit the settings, but to no avail.
The solution can be found when clicking on “My Account” in the top right corner.On the page that opens, find iGoogle in the right column, and click on Settings next to it. On that page, uncheck the check-mark next to “Show a short description for each feed article”. Then scroll to the bottom and click Save. This page also has some additional settings that I was unaware of, e.g., the size and number of columns.
