More often I'm hearing people describing Twitter as the place to get all of your news and to connect to everything and everyone. More than a few times I've heard people say RSS is dead and Twitter now owns the empty hole in your soul that can only be filled with up to the second news. They may be right, but there's one hole in my soul that Twitter couldn't fill and that a good old fashioned blog could.
I've been playing We Rule on the iPhone, which is a Farmville clone (cue the moans and groans). Anyway, there's a social component to the game and I posted up my Plus+ name (which We Rule uses to connect players) and got only one reply. I then posted my name on a We Rule story on tuaw.com and got 20 replies that night (and they continue to come in as I type). So, maybe it's not a shocker that a specific story and a comment posted on it would garner more results, but consider the fact that I posted my name on Twitter in a standardized format.
There's an in-game feature that spams Twitter saying you're looking for people to play with. It's done in the same format every time and only the name in the post is different. You can do a search for that right now and you'll see tons of people looking for each other. Now, I'm just one person, but it's worth pointing out that a blog comment in the right place can be far more productive than shouting into the Twitter abyss.
Oh yeah, add Circk on Plus+ when you get a chance. :D
