Here is a screenshot of what I am seeing.
As you can see the tag description is broken. Instead of spreading across the width of the page, it just looks like a column. It only started happening to me couple of days ago. This problem occurs on both Firefox (10.0.2) and Chromium (17.0.963) on Linux. Screen resolution: 1920x1080.
** New Information ** The issue only happens on the landing pages of half the tags that I visit.
The list of problematic tags:
List of tags that are fine:
I only verified the tags that I follow.
I noticed the difference between the pages that look fine and those that do not. The tags with featured tab seem to have problems. While those that do not have the tab are OK.
EDIT It seems to have been fixed as of March 14, 2011.
I am not sure where to report bugs, so if this is not the right place to report bugs, please let me know where I can do so.
