We all love Computer Science - Stack Exchange, but there is a whole world of people out there who need answers to their questions and don't even know that this site exists. When they arrive from Google, what will their first impression be? Let's try to look at this site through the eyes of someone who's never seen it before, and see how we stack up against the rest of the 'Net.

The Site Evaluation review queue is open and populated with 10 questions that were asked and answered in the last quarter. Run a few Google searches to see how easy they are to find and compare the answers we have with the information available on other sites.

Rating the questions is only a part of the puzzle, though. Do you see a pattern of questions that should have been closed but are not? Questions or answers that could use an edit? Anything that's going really well? Post an answer below to share your thoughts and discuss these questions and the site's health with your fellow users!

See here for the first review in May 2012. There was another one using the queue in November 2012, but I don't think there is public record (yet). –  Raphael Feb 15 '13 at 7:02

Each of the ten questions could be declared "Excellent", "Satisfactory" and "Needs Improvement". The system calculates a score by substracting the "Needs Improvement" votes from the "Excellent" votes.

In November, this was the result based on 18 participants:

  • 5/10 questions in [7..10]
  • 4/10 questions in [1..5]
  • 1/10 question with -1

In this latest feedback, we had 23 participants again, voting:

  • 4/10 questions in [11..14]
  • 3/10 questions in [2..5]
  • 3/10 questions in [-6..-1]

So, arguably, our active users think we perform bad on more questions, but somewhat better on some.

I think it wasn't a good sample. –  Kaveh Feb 24 '13 at 5:03

@Kaveh: Well, it was random. 10 out of three months worth of questions is not a large sample, so it may have been skewed. –  Raphael Feb 24 '13 at 15:45
