About a year ago, Danbooru rolled out a system to obscure the uploader of a post, replacing it with an idea called Top Tagger. The top tagger is whoever adds the most tags to a post. This was an attempt to discourage upload sniping, since credit would be rewarded not to the person who uploads the post first, but whoever supplies the most information. At the time of release it was estimated that about 5% of posts would change attribution.
Running the analytics now, it's closer to a 2% change of attribution.
Perhaps uploaders are more incentivized to provide more tags on the initial upload. There's definitely been a trend towards that, but it's not clear there's any correlation to the top tagger implementation versus just a general increase in tag usage.
So from my perspective, the experiment was a failure. I plan on rolling back most of the changes to simplify the system.
I wanted to create this topic as a forum for discussing thoughts, ideas, and feedback.
