Why not include a "YCombinator Comments" link within the body of the article in the feeds?
What I'd like to see in the feed is some indication that the link points to an external site. We get that locally, but not in the feed.
Edit -- that looks unclear upon rereading. When we see an article in the list on news.ycombinator.com, it looks like this:
Y Combinator a new twist on finding hot companies (mercurynews.com)
The same article in the RSS feed doesn't show the (mercurynews.com) part. It would be convenient to have that in the feed as well, so we know that we need to pop two new tabs for that article, rather than just one.
google reader and their home page thing both show these links along with the main link.
edit: there was an example but it's getting destroyed. can I wrap code in something so it gets put in a pre? just go look at reddit's rss:
edit 2: while your making rss changes you could at a link tag to the head so browsers know the rss is there (replacing the "-lt-" and "-gt-"): -lt-link rel="alternate" type="application/rss+xml" title="RSS" href="/rss" /-gt-
