       | I wish there was a concept of paid expert reviews on
       | Amazon/everywhere. A general review system works well (ignoring
       | review gaming) when your concern is "Does this shirt fit?" or
       | "What's the build quality?", but fails when one expert review of
       | "This device is fundamentally unsound," gets drowned out by
       | reviews on the more easily testable aspects ("The band is really
       | comfortable!").
       | 
       | A great example would be when Benson Leung was testing USB-C
       | cables on Amazon to see which were standards compliant.

               | The suggestion is that negative reviews are suppressed.
               | Communicating a negative review through a facially
               | positive review would help avoid that.

             | leave a stellar review for the restaurant.

         | I considered doing this once, a few years ago, but I couldn't

         | It's pretty frustrating that when you're shopping for a laptop,
         | nobody can tell you it'll suspend properly under Linux. Or when
         | you're shopping for a bike light nobody can tell you whether
         | over the summer it'll self-discharge to the point it bricks
         | itself due to cell imbalance. Or when you're shopping for a
         | microsd card, nobody can tell you.... you get the picture.
         | 
         | But to produce honest reviews, I couldn't accept free review
         | units, kickbacks or affiliate money. And people shopping for
         | laptops and bike lights don't need a $$$-per-month subscription
         | to my newsletter/channel/patreon, they just need a few yes-or-
         | no answers.
         | 
         | And there's a huge amount of churn in products on sites like
         | Amazon; you wouldn't just pay for 40 bike lights, review them
         | all, and solve the problem forever. Different models and brands
         | appear all the time.
         | 
         | And even then, just because when I reviewed that microsd card
         | and found it had great performance, nothing stops the
         | manufacturer substituting cheaper components later on, without
         | changing the part number; it's not like there was a
         | specification _promising_ the performance I observed in my
         | review.

           | That said I'm a little curious if any kind of Gell-Mann

               | It's the silly bifurcation between Garmin Connect and

               | seems like an arbitrary accident of corporate history and

       | 
       | Perhaps don't buy this watch if you live in a crowded location
       | and take public transport a lot. For everyone else, seems really
       | unlikely that the people you interact with will have setup a
       | malicious attack for your watch brand. I don't think wardriving
       | smart watches is a thing.
       | 
       | I'd only suggest that if the watch supports putting a credit card
       | on it that you rethink doing that.
