Bring back "Popular subjects" tag line

Please, turn back "Popular subjects" string that existed in previous versions.

We consider it is a useful tool for newbies navigation. Also it is the most attractive place for popular subjects - all mass problems will appear there quickly if a lot of users post similar complaints.
In addition, in one of other ideas I've posted, I asked to hide, disable Sidebar where tags are visible now. So the is a proper place for tags.
