Well I would have been able to look up the word "Mayyyybe" for a start 
It would help with tracking phrases, rather than single words, or compound hashtag words.
It would also help with finding and blocking/defederating botnets/sockpuppets which copy the same messaging to lots of accounts to steer public opinion. Without being able to track them it's a perfect cover for astroturfing and propaganda.
