I came across "You can do no worse than" in the following article:
You can do no worse than follow the regular updates that ESA astronaut Luca Parmitano is posting in his blog as he conducts his Volare mission on the ISS. He has provided fascinating, first-hand reports on life in space, handling fear, the mishap during his spacewalk and much else (Luca also has a Facebook page).
Logically, I would have expected You could do worse than [x]You could do worse than [x].
Is "You can do no worse than" commonly accepted in everyday conversation, like I could care lessI could care less which is bemoaned in Weird Al Yankovic's Word Crimes?
