This is by no means an exhaustive collection. In fact none of these blogs are those of developers. Those you can always find at the Ubuntu Planet. Some of the famous Linux magazines are not here - the objective behind this list was to create a list of less-known Ubuntu Blogs with real life Ubuntu experiences - to make it easier for me to find what they find interesting or disgusting in Ubuntu.
Update: There is a planet for all these blogs where you can submit your blog too.
