I write reviews because I want to read them.
When I do read them I often look to see what else the person has reviewed. I suppose I want a handle on who is writing.
If, for example, I'm considering a trip to a very expensive restaurant I want to read reviews by someone who has been to other similar restaurants. If my interest is in a particular area and am looking at hotels I sometimes like to know if this person is a party animal, a museums type person or a hillwalker. It's useful to also see how many stars someone gives things...
Not everything a person does/visits/eats can be 5* surely!
I do exactly the same, especially when it comes to holiday/accommodation reviews. You have to read between the lines, but you do become very good at spotting the fake reviews!
