When I had enough rep to review I had no idea how that works. I looked at it and said: Ok, I come back in a few months when I have a clue about it.
I could of course have read a handful of meta posts about it, but I was too lazy for that.
Long story short: I am sure many users would review but have no idea about it or they start reviewing and don't do a good job at it.
Please build a guided tour on how to review.
- It could be like the site tour we already have.
- And include some example test reviews to explain common scenarios
- We could also give a badge for taking the tour
