Saw this in use on The Gem City blog– and thought it was cool- it’s in his right sidebar. We’ll look at it some more- but, seems like a really easy way of doing what Dayton Most Metro has done with mapping- and this lets anyone and everyone post!
About – Platial.com
Platial enables anyone to find, create and use meaningful maps of Places that matter to them. We hope it can connect people, neighborhoods, cities and countries through a citizen-driven common context that goes beyond geopolitical boundaries. We are building it, because we adore Places
It works with other CMSs but- we are most likely to like it on WordPress.
