Thanks all for answering/commenting, especially the ones with criticism and critique: those helped me best at getting a feel for how this should work.
I have upvoted the answers and comments that helped me in this, and accepted the answer that for me explained the human/communication aspect of it best.
Please also read Andrew's answer below, as he too clarifies his comment.
Please read Eugene's answer below, as he clarifies his comment and makes his statement much more balanced.
Somehow my answer on using Acrobat for handling PDF caused some stir.
With stir, usually comes downvoting.
Apart from the my impression that quite a few people dislike big name companies (Adobe, Microsoft, Oracle, even Google), and therefore might have downvoted my answer (hence the two edits of my answer to clarify it), the first comment on my question strikes me:
No idea could be worst than this. Acrobat is both monstrous and overpriced, not saying that Adobe's licensing and purchasing policy is next to useless in many regions (consider OP's location) – Eugene Mayevski 'EldoS Corp
Note the OP Jlouro is from Lisbon, Portugal, which is a developed country with quite a few very nice and very profitable IT companies.
I flagged this comment for moderator attention for a couple of reasons:
First of all, the language used in the comment is very debatable.
Personally, I find it rude and offensive, from any commenter.
But as moderator meagar pointed out, flagging is for "contains content that a reasonable person would consider offensive, abusive, or hate speech" as quoted from this flagging post.
I'm not sure I'm a reasonable person for a comment from a generic commenter; others need to access that.
Second, and more importantly, this comment is from Eugene.
Usually, I highly value his comments and answers.
However, Eugene is CTO of Eldos Corp.
Their product SecureBlackBox contains package PDFBlackbox directly competes with Adobe Acrobat.
I think as a competitor, you need to be extra careful in commenting.
That is the true reason I find this particular comment offensive and needs moderator attention.
I think the 'thanks you for wasting my time as a 10k moderator' from moderator Andrew Moore is very much debatable too.
It is at least a very impolite start of a comment, clearly showing he did not do any investigation, and did not count to 10 before posting his comment.
For me, such a phrase, coming from a moderator, is on the edge of being offensive.
I didn't mark it as such, as I respect moderators, and want to keep some room for discussion before marking it.
So finally the questions:
- What do you think of Eugene's comment?
- What do you think of Andrew's moderator comment?
- Did I react in the right way in this comment thread?
Thanks for your insight.
Even with quite some reputation, SO and SE keep to be a big learning experience for me.
