I implemented the Thesis wordpress theme across all my sites as well as sites that I manage for others since 2011. It is a wonderful theme that has enabled me to create content rich sites without needing to know programming.
As I could hardly find any online guide for Thesis version 2.3 and above, I went through trial and error in trying to figure out. It is also with Thesis wordpress 2.3 that I fully understand and appreciate the drag and drop functionalities of the site.
Below are some tutorials related to Thesis wordpress theme version 2.3 (many of the functionalities also apply to the new version 2.4).
