I've noticed a couple of questions that have all of the tags:

* oracle
* oracle-11g
* oracle-11g-r2

Ideally, the tagging would support hierarchies, and know that 'oracle' is a broader term of 'oracle-11g-r2', so we didn't have to put on the redundant tags, but I don't think it currently does.

So, just as a best-practice type thing : should we be tagging at this level of specificity? If we should, should we also be tagging at the broader level as well?
