Alternately, you can control whether you see what individual people you follow are retweeting with "Turn off retweets": https://twitter.com/following
>/following yea really wish you could do that with likes too!
Yes you can, not through an official setting unfortunately. But as TylerH said you just say "I don't like this tweet" on a few of the tweets that you see because "person X liked this", then refrsh your feed and they're all gone.
Maybe after 6 months-ish they come back, but you notice it really fast since suddenly your twitter feed sucks. Just do the "I don't like this tweet" trick again.
The only 'likes' I see now is if multiple people I follow liked a tweet from someone I also follow. Usually those are good quality.
