A screencast on using PG to handle stuff that is often stored in noSQL databases would be interesting. I'd be interested in both using PG's new noSQL capabilities but more importantly also in walking through creating a Schema for the data (and the tradeoffs). I'd suggest mining some Tweets with metadata from the streaming API (JSON) and using that as a running example.
