Storing Blog Posts -> The Power of B-Trees

[Robert Dionne]

The new chapters look great on a first quick once over, well done!  
"The Power of B-Trees", while a very interesting section, seems to  
come out of no where.  I'm wondering if it should be part of an  
internals section. It just strikes as a little too much of a jump in  
topic, especially given that one of the cool things about couch apps  
is that anyone with minimal html/css/js skills can use it.

Just my two cents trying to wear the hat of an end-luser.
Best regards,

Bob
