We have moved to sourcemap.com, a completely new version of our free platform for researching, sharing and optimizing supply chains. There's nothing you need to do except register for the new website and we'll take care of migrating your data from the old website (this might take a couple of weeks). Here are some of our new features:
New Map Styles

The new Sourcemap supports the creation of different kinds of supply chain maps, including directories of suppliers (left) and maps with multiple tiers (center) in addition to our classic single-tier maps (right).
Media Pane

We're making it easier to document the story of products through embedded videos and photos: just enter the Youtube link or the Flickr set ID under the 'Media' tab and Sourcemap automatically opens the movie or photo slide show whenever someone clicks on a point.
Impact Weighting

Another big request has been to add a visualization of where impact is greatest along a supply chain. That's why we've added filters to each map: if you choose to show the weights and carbon footprints at various sites along your supply chain, you'll be able to toggle between the simple map view and a weighted visualization that shows impact according to the relative contribution of each site in the supply chain.
Drag-and-Drop Supply Chains
For the first time, you can create an entire sourcemap without typing a single word! You'll notice the new "Add a Point" button at the bottom of every map; this adds a point to the map that you can drag into place (or specify a location the old-fashioned way). You'll also see a new "Connect" button in each point's edit window; click this to connect this point to another one on the map.

you still need a list of the info and not just a map

I agree with Steve, there should be some way to see citations for the data points. Love the data viz, but this is absolutely necessary to keep information verifiable.
Adam and Steve,
Thank you both for your comments. We're listening – and we are working to add references, both to the source documents we use for carbon footprints, and to external resources that map creators may want to cite independently. You'll see these improvements (and more!) in Sourcemap 1.2, which is slated for release in December 2011.

State of California just passed Supply Chain Transparency Law (effective from 1 Jan 2012). Visualizing the Social Impact of Supply Chains will deniiftely help small and medium size companies tackle the issues by pinpointing suppliers they have to pay close attention to.
