I think that's a good idea
I would LOVE to have shouts implemented. I cannot tell you how many times I've wanted to comment on someone's profile already but kept forgetting I couldn't. For me, I think this is why the site feels so lonely and isolated. I understand that there is a note system, but for little compliments and things that you don't actually want to start a conversation about, shouts would be perfect.
YES! This is my personal ideal profile layout. Nobody really seems to care about activity anyways. x3
