Usability enhancements for The Housing Bubble Blog (http://thehousingbubbleblog.com)
The Joshua Tree Extension adds usability enhancements to assist in reading Ben's Housing Bubble Blog, including:
* Tracking/identifying new posts
* A navigation toolbar
* Ignore list
* Validation of HTML when adding new comments
Version 3.0.5 fixes a bug where selected text would not automatically be 'quoted' when the user clicks "reply to comment"
