Tweets and In-game Chats

I simply don’t get it. A game is on TV, or you’re at the game, but your focus isn’t on the game exclusively, but on your computer or phone so you can see what other people have to say about the game. In-game chats are on the rise, as are Twitter tweets about the game (or any event, like the Oscars).
So what’s going on is, people’s attention isn’t focused 100% on the game – it can’t be. While the people doing this are people I know, colleagues, and former colleagues, I’ll never be on board with chatting about a game on a computer while the game is in progress.
I’ll admit that occasionally, something of significance or interest is released through these mediums. For instance, if someone notices something that few others did, telling others who may not have seen it can be informative (like if a player doesn’t return for a period due to injury, or a milestone stat is reached). But that rarely happens. Instead, the vast majority of what we get are simple comments about the game/event as it unfolds, 99% of which anyone would know if they’re focused on the TV and not  the computer!
While writing for CapitalsOutsider.com, I sorta have to do it, just in case. I need to keep an eye on what others are saying, just in case.
Now only if I can get ’em to stick to the necessary messages. But I’m one of the few making this argument so I lose.
