Watching YouTube videos together with your friends can be fun, but it's a pain to make sure you're all watching something at the same time. ShareTube does the work for you, syncing playback of videos for everyone in the room. This concept isn't entirely new. We've seen it before with sites like Plug.dj (may it rest in peace) and Dubtrack. However, unlike those sites, ShareTube isn't just geared towards music videos. You can still create playlists of shared videos and chat about each one, but there's no voting on tracks, cutesy avatars or warnings if you play long videos. Instead, you can search for any video on YouTube and add it to the queue. It's a relatively basic site that performs a simple, but handy function.
