Google Data APIs
I have been experimenting with online data applications (for example, my DabbleDB FactBook RSS feed and experiments with Metaweb's freebase.com system).
I am adding Google's Data APIs to this cornucopia of structured data stores. If you are a Java developer, Google's GData APIs download is a good quick start.
GData and DabbleDB are great for organizing your own data online and then using that structured data in your own applications. Freebase.com offers a wealth of "other people's data", as does DBpedia: Wikipedia information culled as RDF data.

metaweb.com and freebase.com
I am always on the lookout for freely available sources of data in useful formats. Metaweb was founded by Danny Hillis and their first public system is at www.freebase.com.
"Freebase is a vast, free, open online database of structured knowledge" - from their web site.
One interesting thing, besides the interesting technology for storing and querying structured data where both the user can define her own categories and use system wide categories, is that the content that hosted is freely licensed under Creative Commons, GNU documentation license, or in the public domain.
You need to request an invitation, and then the documentation provides information on accessing Freebase. I experimented during lunch time with their Python client APIs - cool stuff.
