[General] Tagging functionality on OSAF wiki

[Jared Rhine]

Recently, Mimi asked about putting the "tag" functionality in the 
right-hand navigation available on some pages in the new site design.

Some thoughts and complications:

* The right-hand navigation isn't designed to be on all pages. 
Currently, the implementation requires embedding code/tags into each 
page one wants to have a right-hand nav.  I assume that we want to be 
able to tag any page at all.  So right now, the right-hand-nav doesn't 
seem a great candidate to me.

* Are we sure we want to keep the tagging functionality?  There have 
finally been some use in the last day or two, but we went months without 
anyone tagging any pages.  Even so, no one's asked how to say, search 
through tags yet.

The existing location, now that breadcrumbs are back, is clearly ugly. 
So we're tracking the open issue in bugzilla #8600.  For now, I've 
broken the tag onto a new line under the breadcrumb just to see how that 
looks.

If the conversation goes towards "but I thought we were putting the 
right-hand-nav everywhere", sadly there are technical problems with that 
and that's not what's been built for Preview so far.  If that was the 
intent, let's call that out now and have a conversation about where 
we're at and what we can get consensus on for next steps.
