I often use the “Likes” more as a bookmark than as an appreciation.
Whit the “Likes” mechanism I tend to write my tweets/toots less in a “open to dialogue” form and more in a “look-who-gets-more-likes game”.
In fact boosting/retweeting something that you appreciate should be enough.
Without the social bias of knowing how many people just boosted/retweeted that content, i feel a little more free and responsible in my boost/retweet choiches.
