I get it, and dig it.

Aggregating moods would be useful on a site such as Amazon, where, depending on the technical level of the product, reviews range from sharp and intelligent to blunt and kneejerk. Having access to sentiment analysis would help consumers to quickly see whether or not the product/service being 'mood reviewed' solves their problem or not.

Written reviews are full of conjecture and anecdotes, 5-star gradings may as well not exist for 2-4 stars, so mood is another great metric to add to these tools.
