Seems like such a simple thing to implement, comments already support hyperlinks but descriptions don't? Find myself copying and pasting unnecessarily to look at fellow hacker creations.
HN users can reply to their own submissions with a link when commenting or a comment when linking. Im my experience, links in a comment tends to correlate with driveby posts. But when something is good, I will often pull the link out and post it as a comment.<p>Anyway, because meta-discussions tend to be uninteresting, feature requests tend to be best made using the contact link at the bottom of the page.<p>Good luck.
