Trying to figure out why you were downvoted. Was it the positivity?

The exclamation marks? The lack of pretending to contribute to the conversation?

I downvoted because it doesn't raise any questions or add any information to the discussion.

BTW, neither does commenting about votes ;)

As per https://news.ycombinator.com/newsguidelines.html

"Please resist commenting about being downvoted. It never does any good, and it makes boring reading."

I was merely puzzled that my favorite comment was downvoted to the bottom of the thread!

I am sure the author (who appeared in the discussion here) would have appreciated the positive feedback. Are you suggesting it would have been better to contact the author directly?

It looks like it's been written by a spam bot.

How so?
