Over the weekend we have instituted two additional enhancements to the site.
New Menu Options
In What’s New and all categories, you will see new menu options have appeared at the top. In addition to Latest and Hot, some additional options have been added:

Top: allows you to find top content filtering by certain ranges
Bookmarks: allows you to access any bookmarked content for that category
My posts: allows you to access any topics you have added to that category
Vizualizations
The Graphviz plugin has been enabled. This allows you to create vizualizations using the DOT language. This may be useful when creating tips or other content that requires vizualizations.
