twitter's annotation and metadata

Hopefully everybody has heard that Twitter will release some annotation
feature which will allow to add metadata to each tweet.

I just read this blog post
http://scobleizer.com/2010/04/15/twitter-annotations/

<http://scobleizer.com/2010/04/15/twitter-annotations/>and the following
caught my attention: "There aren�t any rules as to what can be in this
metadata. YET. All the devs I�ve talked to say they expect Twitter to
�bless� namespaces so the industry will have one common way to describe
common things"

I'm just wondering what people here think about this.
