I won't begrudge anyone writing a review for any reason. However, I do think that some are more self-serving, by which I mean that they don't contribute much new information but they do get a lot of thumbs for the reviewer. Even when that's the case, this is Disc Golf Course Review...if you can't write that redundant review here, where can you?? Nobody is forcing anyone else to read through redundant reviews.
However, a somewhat similar gripe:
A course getting a bunch of redundant reviews is like a review getting a bunch of thumbs, or a course getting onto the Top 10 list for that matter. To some extent all of these systems involve feedback loops that amplify and emphasize perceived popularity. That's well and good for people who want to engage in such things, but these statistics shouldn't be taken as seriously as they are (IMO).
This course has 100 reviews!
This review has 20 thumbs up!
This course is on the Top 10 list!
None of these statements are that objectively impressive to me. They are more informative about the way that people engage/succeed in the popularity contest that is DGCR. It's kind of like an election for 7th grade class president: if you're able to sufficiently step back and view it from the outside, you see that it's not all that important. Certainly not as important as it's made out to be by some folks.
Now, before everyone gets out the pitchforks and torches, I'm not trying to badmouth any of the courses that are (or have been) on the Top 10 list. I'm sure they're all great, and I'd love to play them all. What I'm saying is that I don't see much objective difference in value between a great course that's not on the Top 10 list vs. one that is/has been on the Top 10 list. So that particular feather in the cap is meaningless to me.
I mean, heck, there's a pretty extensive thread where people make a big deal out of the weekly changes in the Top 10 list. It's purely amusing to me. Courses come and go from The List at the drop of a single review. People fuss like that's some sort of flaw in the system, whereas in reality that fleeting nature is the heart and soul of the system. On a fundamental level, the composition and order of the Top 10 list are volatile and arbitrary.
