I've learned an incredible amount on this site from the many great contributors we have. One situation that often occurs is that I notice a particularly insightful answer and I click on the user's name to navigate to their profile and then read other answers they've given (typically on similar topics). Sometimes this makes me wonder which answer that individual would put forth as their best on the topic. Similarly, I've made some responses that I thought were better than others, but they aren't all the ones that have been upvoted the most (although perhaps this is just because I'm poorly calibrated regarding the quality of my answers). These considerations lead me to wonder if it would be valuable for contributors to be able to mark somehow a subset of their answers on their profile page as the ones where they think they addressed an issue particularly well.
Update Let me clarify what I have in mind. My purposes, I'm afraid, are somewhat selfish. My objective in this proposal is that I would like to be able to more efficiently learn from others. Now, one way I can do this is to go to someone's page and read their answers on a particular topic, but many of our more prolific contributors have hundreds of answers--too many to read them all. I could just focus on those that have been upvoted the most, but if I don't believe my top 5 answers would be the best overview, maybe they believe the same thing.
Let me give an example: sometimes in my answers I end up addressing similar things, for instance the apparently common belief that in regression the most important assumption is the normality of the residuals (which I think is a less important assumption). I've addressed this several times in different places, and maybe I think I did a better job in one answer than another. If this is true for me, it might be true for others as well. What I'm wondering is, would there be value for the community if, for example, for every badge someone earns, they could somehow mark their best 5 answers on that topic.
