On the far right there are popular tags.
When the mouse hovers over a tag a pop up appears that explains the tag.
Please add a pop up for Hottest and Most Viewed.
Members may want to know the time period for Most Viewed: (start of Q&A, yearly, monthly, etc.)
When sorted by most viewed there are no displayed numbers.
Consider displaying numbers of view for each thread.
