Scoring systems are certainly controversial, but there's not a review section out there that seems appropriate without one. As such, you may see reviews on Blogcritics using a simple scoring system. The scores break down as:
1. Why are you introducing a scoring system?
There are multiple reasons, including benefits for the site. Additionally, this also benefits readers who may want to skim a review quickly and still have a general idea of what the writer was trying to convey. The text is always the single most important aspect of any piece, but the scoring system is there for those low on time.
2. So, a five means it's perfect then, right?
Nope. Here's one great benefit to a five-star scale. When you see a 10, or 100%, or whatever score may be used, it's a supposedly a sign of perfection. Simply put, there's no such thing. On the other hand, a five-star score means it's simply something superb. There's little hesitancy when handing out five stars, which means the entire scale is used. Most sites (in general) will hand out all of three "perfect" scores a year. That's not using what's available, and it's because of the designation the 10 has earned over the years. Not so when you're dealing on a simpler scale.
