You can't always infer that a lot of views mean a lot of unique visitors. I know that when I post a site to be reviewed, I read and reread the responses multiple times - not always from the same computer.
For reviews I usually start by checking page three and working my way to page one, looking for requests that haven't received much response.
You don't have to know a subject to know if the navigation works, if the font is readable, if the site is user friendly. Well, thats where I start anyway. When looking for reviews I have found the varying backgrounds of the reviewers help to create a total picture which is better than a single review from a single so called expert.
