Twitter has a function for identifying content you'd like others to see in your own timeline: it's called retweet. It also has a function for identifying content that is noteworthy but failed to meet the higher bar, and that's called "favorite" (I still prefer "like", but whatever.) At some point Twitter's algorithm began using favorites to serve the purpose previously served by retweets, and the quality of the timeline has been in free-fall since then.
