EDIT:
Instead of emailing to the room you can also add a delicious tag's RSS feed to it (e.g. ff:myroom => http://feeds.delicious.com/v2/rss/yourname/ff%3Amyroom) to cross-post from delicious using your favorite browser bookmarklet.
And as mileszs said (http://news.ycombinator.com/item?id=465772): you can add the room's RSS to a reader (even if it's a private room).
