I think that's an interesting suggestion, and would be a useful feature. It does suffer from the problem that links would only become clickable after a time (having to wait for votes) whereas it's the first few views that really most benefit.

It's a great piece of thinking though - kudos. I've upvoted you both here and there.

Thanks ROG - I figure that at least the first few people view the link anyway before someone posts a "clickable" comment.
