The social-media platform known as Twitter can be used for plenty of good things, and for plenty of not-so-good things.
Here’s one very good thing for which it recently was used: A retweet from Raiders quarterback Derek Carr of a message aimed at finding a missing boy resulted in a reply with information that helped police find him, via CSNBayArea.com.
It’s a reminder of the potency of the device. Carr, with more than 247,000 followers, clicked a button and performed a significant service for his fellow man.
Meanwhile . . . . Never mind.
