Some people write reviews about products thay've never even used, and then complain on forums because Google didn't put their review at the top of the SERPs..
That's to avoid a dupe penalty :). Say you have a soccer blog and in yesterday's match Ronaldo scored on the 44th minute. If you write that you are guilty of dupes since others will write that too, so you say Kaka scored and on the 43rd minute.
Same with reviews: if you say that a tablet has a 10 inch screen the Google gods will give you a duplicate penalty so you change it.
/half joking. JohnMu from Google actually chastised someone on Google forums for having a sports blog based on the games he saw on TV. Didn't seem unique to him.
