Content aside, there are a lot of eBooks published by both traditional and Indie folks that are not formatted correctly. As a matter of fact, I've seen a lot of "rubbish" (formatting wise) from big name publishers who don't know the first thing about digital publishing. Content rubbish has, does, and always will appear, but that is for the individual readers to determine. Format rubbish needs to be addressed, and is in my opinion a much more important issue.
