Big tech companies are making changes to some of the viral mechanics that drew users to their services in the first place. Instagram has started to hide "Like” totals on posts in the US and will soon do it for the rest of the world. Twitter Inc now gives its members the option to hide replies to their tweets, allowing them to partially conceal the ugliness and combativeness that’s endemic on the service.
And Amazon.com Inc, a pioneer of crowdsourcing product reviews, recently changed the way it displays customer feedback at the top of all product page on the site. It now prioritises ratings from customers over those who took the extra time to write a review. It’s the first such adjustment in 20 years.
