OK, this may be a a little-known feature but HN has this built in. Go to https://news.ycombinator.com/saved?id=cowbell and you can see all the stories that you've upvoted. That way you don't have to leave bookmark-comments.

Edit: P.S. Usernames here are small and grey. Probably no one looked at your username before downvoting that first comment. If I made comments like the ones you've made I'd get downvoted too, because no one knows or cares that I have 26k karma.
