PostMapper is the map based social bookmarking platform, where you can share and discover geographically oriented web content.

Instead of saving bookmarks in your web browser, PostMapper users can organize web pages by location and save them to their own map. You can also share and find web pages, photos, videos, and more by searching by location or tag name.

Here’s a synopsis :

• Organize your bookmarks by location
• Explore the map marks of others by location, tag, or user
• Download map marks as KML or embed them into your blog or website
• Create a map based navigation of your web pages or blog posts
• Bookmark web pages, blog posts, images, video & anything else on the web
• Posting is easy via Bookmarklet or Firefox toolbar (a la Stumbleupon)

Embedding a Postmapper map in your blog or website is an easy. Use them to map your blog posts, places you’ve been, or keep up with trends in your town or across the world.
