Attitude?

Well, I think everyone is fed up of reading my posts related to anywhere abroad. So, I thought I'd return to familiar territory. OK, the subject of this post (more of a discussion actually) is attitude and the many forms that it comes in.
Let me first define what I mean by attitude: A person's way of interacting with others. For example, is someone diplomatic or blunt? That sort of thing. If you prefer some other more appropriate term, go ahead and use it.
The question I wished to ask was this: Is a straightforward (blunt, in-your-face, says things as he/she sees them) person better off than a diplomatic person? When I say better off, I mean in a personal way. Who would you prefer to talk to and why? Personally, I'd like to talk to someone who is blunt. At least I know that he/she isn't just saying things to please me. With a diplomatic person, I'm not so sure. Nothing is more frustrating than getting a diplomatic person to take a stand. Just ask Poi and me. We had probably the most diplomatic person as our room-mate. It was impossible to get his opinion on anything without a maybe/if/but.
I'm on the other hand, quite blunt. At least I was until it really hurt me. I got sidelined when I arguably deserved better. (I think everyone knows what I'm talking about) Ever since then, I've made a conscious effort to be a little bit more guarded in my speech, a.k.a. Diplomatic. But is this what people want? To have everyone talking in words that leave everything ambiguous? I guess so. Sad.
I'd have thought we require more clarity, rather than more ambiguity. What do you think? Are we better off with diplomatic or blunt fellows around us? Do tell me, I'm all ears. (Just look at my pic carefully, will you? :D)
