1. add the ability to "favorite" from the front page. I rarely "favorite" anything, because I grew accustomed to using "upvote" as the mechanism to save stories. I would switch, but that extra little bit of friction of needing to click through first, means I stick with my old habit.
2. Add "favorite" for comments as well.
3. (maybe) - consider renaming "favorite" to "save"? Possibly people who are used to seeing the "save" link on Reddit would find that more intuitive.
dang: if you get rid of it please don't do so w/o notice so that those of us who do use it can export the links first.
Heh, there ya go. I'm one of the people who uses the favorite feature (albeit sporadically) and I didn't even know you could do that.
Yeah, surfacing the UI element for "favorite" to make it easier to find would, IMO, make it a lot more usable.
For now, I have a bookmarks folder for stuff like this.
