Most sites that I work on have Full HTML as the default filter because most of the users prefer to use a WYSIWYG editor like FCKEditor. When using a WYSIWYG editor you need to have the Input Format set to Full HTML or all the WYSIWYG goodness won't show up.
Personally I prefer not to use a WYSIWYG editor, nor do I prefer to use Full HTML as my Input Filter. I like to keep my nodes simple and the Filtered HTML Input Filter works just fine for me.
I find it annoying to have to submit my node, and have to go back and edit it because I forgot to switch the input filter to Filtered HTML.
- Adds a fieldset to the user edit form to allow the user to choose between the filters available to his/her role as his/her default instead of the system default.
- On forms that give an Input Format choice it sets the default as the user's choice.
