I am a software developer for Google, working on the group that does Blogger, GMail, Orkut and other community-oriented sites.
I'm interested in proposing two PACEs to the Atom Publishing Protocol team:
* PaceBatch - enabling batch updates to Entry Collections
* PaceCategorize - enhanced categorization of Atom entries
* PaceIntrospectAsFeed - use Atom feed model for Introspection
