Other GIS Blogs

I have compiled a list of blogs that I have used that I think are very good:

• GIS Tips and Tricks: http://www.aubreyrhea.net/gis/ - This one is no longer updated and is for 9.X, but it is still very useful. 

• F yeah GIS: http://fyeahgis.tumblr.com/

• CartoTalk: http://www.cartotalk.com/ - This is a forum for cartographers. There is a thread where you can upload your map and get critiques. 

• GIS Wiki: http://wiki.gis.com/wiki/index.php/Main_Page 
• GIS Wiki GIS blogs: http://wiki.gis.com/wiki/index.php/List_of_GIS-related_Blogs - A list of more GIS blogs. 

• A Cartographer's Toolkit: http://www.gretchenpeterson.com/blog/
