What do you think about CTPs?

Brian Harry wants to know.  We've always had a concern about the quality of the CTPs we release, but are torn between increasing the quality, but reducing the frequency. 

What we found with the monthly frequency of CTPs as opposed to the classic "wait for beta quality" approach is that we received more valuable real time feedback on features in development that allowed us to make changes. 

How would you like to see us walk this line?
