Widget-based XML
The new blogger beta has a brand new template system. It is constructed in sophisticated XML format and it comes with a brand new cool feature, widgets.
Unlike the classic method, the new system is difficult to understand and very much hard to edit (in terms of looking at source codes, and to design new templates from scratch). It kinda limits creativity for all my 14 year old design girls. So, with the countless amount of time I have on my hands I decided to express my love for Blogger and XML by doing the dirty work.
Oh by the way, yes it's free.
