People who read an article by an author, or visit content associated with a tag, will be plotted on a map of the US/world. THe mashup will plot where the readers of the content come from. We publish 1500+ articles a month and have over 55,000 articles, over 8000 tags, over 10,000 member writers we'll be able to use this with.Readers will even be able to see a map of who has looked at the same articles. Imagine you are thinking of moving to a new location. You take articles you've read and look at maps of where the readers come from. That might give you an idea of where you'll find like minded people.We're also going to be adding polling to the site shortly, so we'll be able to map responses to polls. Our polling system will be open to any member to use, so it will be easy for anyone to create a poll, then map the results. This will be invaluable for campaigns, causes, advocacy orgs... Then, we also collect demographic info, so we'll be able to add that layer to the mapping.
