As you probably know from reading the manual, the at-a-glance page is not subject to the story list order used in other sections of the site, but is supposed to rely solely on the date/time of the story itself.
Sometimes the at-a-glance page has not listed the most recently updated content, but instead has listed things randomly.
We believe we have this fixed in the Feb. 2 update. If you find examples of it not working, please let us know.
