Sometimes I find a two year old post on HN that I want to comment on, but it's "closed" - the reply button is gone. HN should implement that when N hits from Google occur, it bumps it back to the front page and makes it able to be discussed again.

More seriously though, Stack Exchanges platform isn't designed to handle opinion polls and endless discussions. You might want to consider asking the question on a site geared to opinions and discussions such as quora or reddit.
