Ask HN: How do you manage your favorite submissions?

Hacker News is one of the many sites and services where I save favorites (reddit, GitHub, stackoverflow, Digg Reader and others)

It would be nice to have an aggregator. This is something I have thought of building myself, but I have no experience making web apps.

I have begun aggregating my favorites for various general topics by starting a google group on the topic and posting my HN favs to it.

You click "favorite". It's right there next to "flag", "discuss" etc.
