Their are people who will accept your review for what it is, which is YOUR opinion. Their are others who will pick apart every last detail of your review. Sometimes I feel that people are a little hard on others, but maybe I do not have their level of experience or knowledge on subjects to have the right to feel this way. Some people that have Webtv's are constantly being rated lower. If I honestly feel that this person is giving good quality advice based on their experience then a few spelling errors would not damper my ratings.
Lets take for example a review on car seats.
Maybe a reviewer has the same seat that I use for my son. She had a horrible experience with the carseat and it put her child in danger. This reviewer had a few spelling errors or maybe did not include the color of the seat. She felt that saftey issues were more important than the color of the seat. I am a relatively simple person.
