I was curious about the unique number of reviewers, and (from your CSV) it seems that 6838 different FF.net accounts placed reviews. That's fewer than I expected given the 9.6k favs and 8.6k follows.
Of course, that guy named "Guest" was pretty prolific.

Remember the 1% rule: 1% of your viewers will interact or participate in a meaningful way (and I've seen videos on YouTube with more than 100x views to total votes). So actually, given how much easier it is to favorite or follow than to write a review (however slight), a 6.8 : 9.6 ratio is pretty impressive.
The odd thing there for me is that favorites outnumber follows. I would have expected follows to be a superset of favorites...
