nice how I disagree in my own answers. In one second I thing I got it, 
in the other second I read some posting in the NG and everything is just 
upside down and confusing again. Maybe we both try to find "the" proper 
way for doing things, but like in life there are several ways to get to 
the same place. But some "best practice HowTo" would still be nice to 
have :)

 From what I see and understand, your code should work:

$query = $this->queryFactory->create('Tx_BlogExample_Domain_Model_Post');

This seems to be correct in my eyes to get a valid query object for the 
posts. But I can't tell if somewhere in the extbase magic the 
queryObject is relying on the repositoryObject. So I'd better be quiet 
and listen on Jochens suggestions now - because I'm myself, just like 
you, a beginner in this stuff.

Although I'm no expert, I'd say so. Using a empty or negative limit 
would probably also do the trick and might not be wrong from a technical 
side, but is not that self explaining like the other methods. And AFAIK 
DDD is about to make stuff that easy to understand and work with that 
even customers understand what to do - right?
