It's not for casual users. The only way it adds value to your life is if you use it more than casually. It's a symbiotic thing. The more info you feed it, the more valuable the information you receive on it will be to you.
Also it was a revelation for me as a nontwitterer to go barhopping with a friend who tweeted his itinerary and we met up with a couple of strangers that followed him online. Like, oh, social media can actually lead to social interaction, amazing. Probably not typical experience but a few people I know would never willingly give up on such a powerful networking tool in their niche.
