Practically speaking, I wonder how long custom tags will remain as flexible as they appear in the spec. It won't take long for search engines to decide their preferred tags, how they're weighted and how they relate. Then our tag schema will pretty much have to follow suit to rank well. It'll be like the rel naming conventions, only on a larger scale.
