Q is for Quality

This is a topic that I've seen discussed in a few different writing chats over the last couple of months. The topic has to do with quality, in particular should readers expect self-published books to have the same quality standards that they expect from "traditional" published ones.

There are some who say that because the books are self-published, they shouldn't be held to the same standards. That people should, essentially, expect less from a self-published book.

Others on the other hand, think that because of the stigma that many have against self-published work that it's almost necessary for the self-published author to focus even more on producing a quality product. That some will even hold them up to a higher standard than a big name published book.

So, I'm curious what bloggers think.

When it comes to quality:
Do you think self-published authors should be held at a lower standard?
Or should they be at the same standard as other published methods?
What do you think?
