You see it all the time, SEOs requiring content to be a certain length or else be penalized by Panda!

A Google Webmaster Help thread has a has Google’s John Mueller reiterate this.

He wrote:

It is about the quality of the content, not the length of the content.

Then someone else comes in and says “if write short length content may I penalize in future, Ii need straight forward answer.” John Mueller responds:

So again, it is not about content length, it is about content quality.
