I developed and launched Planet Minecraft, with the main goal of sharing Minecraft projects for feedback, inspiration and collaboration.  There's quite a few features already in place and more under development.  It went live last week and community feedback has been invaluable.  The more feedback the better I can make the site.

A bit about the site:
Planet Minecraft allows you to upload and update your projects anytime you want.  You can upload images to create an image gallery, add a youtube video, project description, project server & /warp, MCEdit Schematic file, World Save link, MineSeeder Code and current progress.  Visitors can comment, vote and get involved if your looking for help.  Project views, downloads, favorites, comments and votes are tracked and influence it's position in the various ways you can browse all projects on the site.  Projects can be filtered, sorted and searched. 

I welcome all critiques, questions and feedback.   Here is my member profile on the site to see some of my projects.  Hope to see some of yours.
