Imagine having your own private database of every person you’ve
ever stumbled across online, and being able to download their
vCards into your address book. And every event, which you can
download into iCal/Sunbird/Outlook. Plus a list of all the
Creative Commons-licensed content you’ve ever read, which you can
repurpose — legally, according to the terms of the license.
Now imagine searching such a database. And subscribing to your
search results as a syndicated feed.
It’s coming. Within weeks, not years. All the data is out
there; people are publishing this stuff anyway. If they publish
it just 1% better (with appropriate microformatting), I can get
1000% more out of it.
