I don't believe nested tables are actually stored in the same table as the parent table, so there are issues with the argument that they have any particular benefit over traditional related tables. Some might argue that if you want to store self-contained document-oriented records, you should store the data in an XML column or store a big string of JSON and use something like PL/JSON to work with it. Personally, I try not to get too bogged down about what certain people think and just go with whatever works right for me, and I like using the nested tables solution for tags, whether or not Tom Kyte thinks I should.

I guess what I like about them is it allows you to use Oracle to store data much like a document-oriented database (e.g. CouchDB) would - with everything related to a record self-contained.
