We just updated the site and we've made some big changes. More detailed release notes are on the way.
Clicking on "Explore" now takes you to a display of all the most recently modified maps, the most recently active people, and the most common tags. To find all of your maps and Places, click on "Your Platial."
Today Nearby allows you to see the freshest pictures from Flickr, videos from Youtube, news, and of course the most recently added Places from Platial for the part of the world you're interested in the most.
We've worked hard on these new changes and we're looking forward to hearing from everyone to let us know how you like them.
