Ask HN: Can I aggregate my up-votes on HN into a personalized RSS feed?

I spend a lot of time on HN up-voting articles that I find interesting and worthwhile, but in order to share with friends I need to copy the URL, open a new tab, navigate to Twitter or Google+, write a brief summary or introduction, and then publish it.

I've been thinking that it'd be more efficient to provide an RSS feed to my friends/colleagues containing the articles I've read and found newsworthy on HN. Is there anyway to accomplish this?
