Specially the ones I'm interested. It's mostly others' comments that I see downvoted. With mine I see another problem: responses use to be completely unrelated to the point I was trying to make.

I'm not an English native speaker and ellaborating in technical topics is more difficult than in pop-sci or net folklore. Spending a long time composing a comment just to see it misunderstood or downvoted is discouraging.

If you take a look at my recent comments, there was someone complaining that he could not control his browser completely. I've had some success using Chromium Embedded Framework. I suggested that and got a -2. Why? I don't know, because it was a post about Firefox? So what? Someone that disliked another thing I said?

It doesn't matter, but it happens to be my most technical comment in weeks, maybe months. Other of my comments with platitudes are much upvoted.

Most discussions are polarized. Sometimes I start to write a comment writing a disclaimer saying that I'm not in side X, but... when I notice that, I stop and cancel. And that's not only politics or bigco.

I completely understand you, friend. Personally given up trying to pacify other commenters and just speak my truths. That doesn’t mean going out of my way to offend people with my words, I try hard to NOT do that-but I’m also not going out of my way to appease them either.
