"Like" was ruined when Twitter made it republish tweets, making it practically identical to retweet. It had been useful to mark posts for later review. Without it at all, there will be no way to "save" a tweet.

Edit: I was thinking of favorites. I used favorites as bookmarks, so I got it mixed up.
(I think making Favorites/Likes act like retweets was a terrible idea - thankfully I never saw them in third-party apps, but it made the website a horrible experience when you see what the people you follow were liking.)
