Yes, that's what I said. You vote ++ on something if you think it's a good contribution. I think your confusion comes from your belief that a highly rated comment should demonstrate some amazing perl skill. A simple comment that many people find worthwhile might get a higher rating than an amazing perl trick that wasn't as generally useful or just didn't get seen by as many people.

I get "sad" :)) when I see that I was also downvoted for what I proposed as discussion.

You were probably downvoted because we're all sick of talking about XP and would prefer to talk about Perl.
