I think "real" reviews should require I AM tags, pros/cons, title, and over 500 CHARACTERS (not words). That would be about 100 words. Those would count toward people's review count.
I think the other things (ratings/quick reviews) should not be counted toward anyone's rep.
Here's where I get confused. I will go to a product and see that are 4 "reviews" and there are three thumbs up and one thumbs down. I will read the reviews and the real reviews all have the thumbs up. Then I will get to a no word rating with a "This stinks" title and a thumbs down. I think it really hurts the rating system to allow people to rate things without at least explaining why something stinks (They can muster a line or two).
I think we need reviews of all lengths and I have found short reviews to be helpful to back up the longer reviews' data. But I really don't like empty reviews with just a title and a rating or reviews with three words. I think anyone, even the busiest person on earth, can manage a couple of lines of text. They took the time to go to the listing and rate it, how hard is it to write a few words about that rating? Even: "This mascara flakes and clumps. It's also too expensive," helps me to understand why it stinks.
If we have ratings that are wordless, I don't think their ratings and thumbs up/down should be folded into the product or service's overall rate. I just don't think it's fair to the product or service.
I understand people not wanting to bother with tags, pros and cons, or verbose reviews. But I really believe people can muster up a FEW words to back up what they are rating. As you can tell, I am not a fan at all of the wordless reviews/ratings/quick reviews. I put no credence at all into them and I feel they are not helpful. If anything, they're confusing. If we, the long time members, wonder where the review is when we get to a rating, what do visitors think?
I definitely agree that the ratings/quick reviews should be at the bottom of all reviews.
The filtering and other things mentioned are all good ideas.
EDIT: No lie. I just read this after doing something else and I thought, hmm, that person's a jerk. AND IT WAS ME. I don't have my pic so I didn't know who wrote it. Haha. I thought I'd share. I'm just cranky. Sorry.
