I’ve noticed this every time I start a new job. How long does it take before you stop referring to the company as “you” (as in, “What did you guys mean to do over here…”) and when do you start using “we”? Twice now my new bosses have caught me and said “Feel free to start using ‘we’ any time, you’re part of the company now too.”
I think the distinction I make is that when I’m speaking of the efforts that came before me, I say “you”. After all, it’s not like I want to take credit for their work. I can’t say “Here’s what we meant to accomplish in version 6.1” if it came out before I was around, right? Once I’ve got new features added to the product I’ll feel more comfortable saying We.
