I agree: it should be a great addition, but it hasn't really been used to advantage. I think the main thing is that it needs some publicity: many people have never even noticed it. I've tried to use it for comments, but it's hard to be diligent if no use of it is ever made.

Another easy thing to do would be to add "Most Favorited" to the "Lists" page. Maybe it would be possible to show the number of favorites that a post or comment, with a reverse link to who has favorited it? Maybe add a notification to the creator of a comment that is favorited?

Possibly instead of just having a link on people's profile page, you could have a rolling list of the their most recent favorites? Or maybe for "person" discovery, you could automatically show who else has else favorited something after you do?

It seems like a good feature to start publicly experimenting with. Announce something, try it out for a week, then post a thread asking people what they think and how it can be improved.

I think adding "Most Favorited" would create a popularity contest and people would start looking for ways to game the system. I don't think favorites should have metrics associated with them because as soon as metrics are introduced people will try to optimize them.

Now that I know comments can be favorited I plan to bookmark comments that include useful reference information on topics I find interesting. Adding counters for how many times the comment was favorited wouldn't really help me with that use case because I doubt anyone else cares about collecting useful references so my favorites would never make it to the "most favorited" list. I personally don't care if I make it to the list or not but I'm certain some people would care and they would go around and start playing a popularity contest instead of looking for ways to favorite information that would be useful to them.
