There's a time for both. Speaking your mind should always be tempered with tact though. I always walk away and think for a bit when I know it's time to speak my mind lol
Already been said but yes a time to speak and a time to hold your tongue.
I tend to speak my mind but dont want to hurt anyones feelings dont mind stepping on toes though
I aggressively say what is on my mind.
I see some good advice here, like know your audience. Sometimes, you can see the tension in others, and they give glances your way, because they know you think like them, and then you maybe feel emboldened. Most of the time, I keep it to myself, unless it is a safety issue. If something really bothers me and it can wait, I try to meet face-to-face with the person later on, and get it resolved. No point embarrassing myself or others unless necessary. And one must weigh the probability that someone else's opinion can be changed. If you can't change things, then live with it or walk away, and stop worrying.

I believe in honesty and saying what is on my mind. that being said, I do try to temper or carefully word what i do say.
I have always been told that I am "brutally honest". I Figure if you are asking me my opinion, why not be truthful about it. A lot of people cant handle it or don't like it, others really appreciate it cause most people aren't that way. My best friend calls me anytime she has a problem because she knows I will be honest with her, and not just tell her something to make her feel better or take her side.
It's always better to speak your mind but sometimes tact is needed as the truth isn't always palatable to some people. But if I'm out and about and I see something that angers me then I will say something
My friends know I'm brutally honest, and I guess they don't mind because they always ask for advice. If you ask me, I will give you an honest answer, like it or not, and it's gotten me in trouble, but at least you know where I stand.
There's a time and place for both. The trick is knowing which and when. I admit that I'm still trying to figure that out.
I am not very good at this in the sense that I tend to speak my mind and why not .. it gets it off my chest and I am too honest and allowed to express how I feel .. I could however be more subtle at times.
I TRY to mind my own business and keep my mouth shut, but...there ARE those times when there are things that I CAN'T simply walk away without saying ...the old "every rule has it's exceptions" thing.
I don't bottle things up, but I am very careful about what I say. Especially in inflammatory situations when others are spoiling for a fight.
However I will speak up for someone/something if I feel there is an injustice or an important point to make. But always calmly and clearly.
Well I'd rather hear an opinion from a quiet thoughtful person than one constantly beating their drum.
If asked, or it's something that will affect what I have a vested interest in - then yes, I will absolutely speak my mind. But listening and gauging the situation is also important, mind.
I am quite a vocal person and will normally say what is on my mind. If it's in reference to something that has somehow pissed me off I become very sarcastic in my responses I will not ever intentionally make a comment that would hurt another.
Speaking what is on your mind- no matter how unpopular it might be ..if people cant handle it..then they are not worth your time anyways.
Usually speak my mind except with family members when it would seriously hurt their feelings or make them feel inferior.
When the right buttons are pushed, I will speak my mind, but other then that, I usually keep quiet...
Sometimes it's better to keep your own counsel; you know what you believe and that should be enough. Tact and diplomacy should be foremost in a group situation.
I'll speak my mind when the need arises. Most of the time, those that don't agree do not want to hear dissention, especially when they have the 'concensus' on their side. In such cases, most people shut their minds anyway. I stand on principle and if that becomes untenable, then I will simply remove myself from that particular situation.
I speak my mind in a very careful way. I get my point across, but leave 90% of what is running through my head to myself. Even when I don't say most of what I think people seem to view me as someone who speaks their mind often. Yet when I say what is going through my mind, unfiltered, people usually find it a bit extreme.
or was that just simply johns??? 
It's much easier to just be the quiet one.
