Who to invoke

It's way more interesting for us to do something than for me to do something.  The collective is a way more interesting voice.  In writing I can choose to write as myself: "I did this, I do that, I think this, I thought that."  I can also choose to write as the collective: "We do this, we do that." or I can write speaking to you directly: "You think that."  I haven't yet figured out which voice or command I prefer.  Does it really matter even?
