> Is HN only about saying nice things about everything?
This implies fault lies with HN. You make the assumption that you are right (despite your PS).
A better question is:
> I'd like to contribute; can anyone offer advice to improve my comments?
Humility, and no assumption.
> I don't know maybe it's me, maybe I have too radical opinions on stuff.
Again, this is conceited. It's not your 'radicalism.' It's your ego talking.
> I am not saying neither that I'm always right nor that I never deserved the downvote.
But your entire comment suggested that you weren't in the wrong.
> I may be alone in this, but I like expressing my thoughts/feelings, as a matter of fact, most of the time I want to make it really clear that what I say is just my the way I see it.
No, you aren't. You aren't "alone" in this. Rather, your ability to communicate effectively is lacking. Indeed, it's very egotistical. You're focused completely on "your opinion" and frankly, your opinion holds no value.
In all your comments, I see you place a lot of value on your opinion. Your opinion can't be wrong, and it's yours, and you'll share it. But who are you that we should care about your opinion?
This doesn't mean you can't offer opinion. It's just that you need to qualify you opinion with reasoning. You can't just state an opinion and expect everyone to see the wisdom.
Listen, you seem like your interested in providing value here. Disagree with whatever you want. But don't just disagree, explain why you disagree. With examples is best!
Do more than ask pointless questions (especially questions that are answered). Anyone can ask questions.
> Vertical list of applications??? Microsoft what have you been smoking?
Provides no value.
> Vertical list of applications? I'm not sure this will grow well. As users add applications, it will make for a lot of scrolling.
Goes further and provides actual meaning. People might still disagree, but now you've explained your opinion.
You've generated discussion.
Hopefully all of this (thread) helps! =)
If I write something like "<something> is a load of crap in my opinion" I don't mind getting downvoted, but a lof of times I get downvoted even when I am strict and technical, and again this won't bother me if people would supply a response.
Having a "well formed" comment simply downvoted is equal to simply replying that "Your comment is so crap that it's not even worth my time to explain why.".
> You've generated discussion.
Yes it seems that there is a way to do this properly, as I wrote I still get downvoted, even when I'm polite, but it looks like the bright people greatly outnumber the others here in HN.
If it's frequent then there might be indeed a problem. Think about and try to understand what PG observed about your comments.
I also often get downvoted. Think of it as just a tool helping to sort comments, not to judge you. I benefit from it too to read the "best" comments first. But when i'm really interrested in the topic i read all comments, even if they are downvoted. I also sometime upvote downvoted comment when I think it was abusive because I know how it feels.
