How are you experiencing the effects of 'professionalization' in terms of contributions and moderation in the current internet landscape? My recent experiences on Reddit and Wikipedia suggest that it's increasingly difficult for new users to effectively contribute without significant karma accumulation or forming relationships with existing moderators. This seems to be a detrimental trend, as it reflects not necessarily the quality of content, but rather a system of social 'gatekeeping'. Do you think the implementation of AI moderators on these platforms would be beneficial in reducing human biases and improving the quality of discussions, by reformulating ideas and correcting deviations from the rules?
