i think goku99 was being sarcastic but thanks for clearing the downvoting up. obviously he's new around here... and my comment was a remote sensing joke.
clearly downvotes are used to suppress views that certain ycombinator members don't like. i would expect that behavior from china and russia, sad to see it here.
In the comment head, click on the time submitted (it's actually a link), just after the author. For example "9 hours ago". You will be taken to a readable version of any downvoted comment.
