I came across "You can do no worse than" in the [following article][1]: > 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 \[x\]][2]. Is "You can do no worse than" commonly accepted in everyday conversation, like [I could care less][3] which is bemoaned in Weird Al Yankovic's [Word Crimes][4]?
