Ok. So the space is too short ( for a full synopsis ). But we ( as synopsis authors ) would invent shortcuts for rating and summarizing the content that would fit to the right or be truncated. And when a user clicks on comments, the full synopsis is always at the top of the comments.

And maybe the descriptors that different users would implement ( like their own tags/ratings for the content ) would become unique to that user, eventually, and have contextual meaning to that author. Each synopsis author would have their own tags that they could reuse. Only people who subscribed to that author could see their synopsis so their silly or cryptic or worthless synopsis descriptors would not clutter HN readers' experience unless they subscribed to a particular s-author ( synopsis author ).

So each user could have a customized right-hand HN site by subscribing to other synopsis authors and each synopsis author would have their own ways ( tags, most likely to start ) for communicating concise summaries/likes/dislikes of the content posted on HN.

But wouldn't a feature such as this take all the mystery out of HN headlines? Or would it add more mystery :) ?

Or would it add too much sub-culture HN? How much would be just enough? ( I hope I am not too off-topic by now )
