I basically agree with this stuff. I doubt many hardcore Emacs users  
choose to switch buffers this way, which requires using the mouse. And  
the part of the behavior that is least useful is that the switch is  
blind - you don't know what buffer you're going to get unless you know  
the current state of the buffer-list.

My objection is to the idea that you don't want star buffers in the  
list. These are also used for interaction with external processes:  
*ssh: host*, *SQL: foo*, *Twit-recent*, *compilation*, *shell*,  
*Python*. It seems ill advised to exclude those from the list.

Where would you suggest showing this information? Some minor modes  
change Emacs' behavior significantly. For example: auto-fill-mode or  
abbrev-mode. If these aren't in the mode line, where do you find this  
information?

Can you describe the use case where you do this? It sounds like you  
have a configuration issue, honestly.

I think the only time I manually switch modes is when I need to use  
*scratch* for something, e.g. I'll switch to emacs-lisp-mode if I want  
to eval some code, sql-mode if I want to write a query, etc.

I should probably write some functions to give me *lisp* and *SQL*  
buffers with the appropriate mode.
