What immediately struck me is having two forms of communication rather than one. I don't like that. The article mentions the company reduced it's email by some percentage in the last six months as if that means something. I know I'm more likely to send a stupid link to a coworker if I'm on chat vs company email.
Yep, you're exactly right. It's like replacing long form time wasters with short form time wasters. A context switch is a context switch whether it's from productive work to email or from productive work to IM.
