You'd think YouTube's iOS app would have had iMessage sharing early on, but no -- sharing clips to Apple's official messaging client has been a cumbersome affair. Not so after today, however. YouTube has quietly updated the app with a direct-to-Messages sharing option. Tap that and you can quickly send a clip to a friend. The video will play directly in the Messages app, too, so recipients don't have to leave chat to start watching. It's a simple addition, but it promises to make life decidedly easier if you frequently express yourself with funny cat videos.
