You'd be surprised in how just about everything in every field how many people buy things simply because more people use it. I'm guilty of this time to time.
Also I don't get this analogy.
I'd rather the numbers be private, popularity sorting is fine enough, and then we could even do better without it.
If we had a sorting system with ratings I'd feel we'd be much more sated in the drive to further promote the best scripts among our lovely scripters.
Though that's not to say the same result wouldn't occur.
But a system where buyers can asses the script based on ratings and a review is better than a peak amount of users (Where some are inactive and don't use the script. or don't even use osbot anymore) & a review is better imo.
But this is also flawed where a script may come in contact with an update and break and someone gives a rating then.
