This is related to this feature which is nice to have on the Careers profile. However, it would be nice to have on any Stack Exchange profile as well.
I'm thinking of a better way to promote the questions/answers you're most proud of, or that you think are really good. A lot of these questions get maybe 1-2 votes and an accept, and that's it.
Currently questions/answers on the profile can be sorted by
votes | activity | newest. Maybe add a new category there -
showcase , where you can manually add 5-10 questions/answers you really like.
If you look at my Stack Overflow profile, the top answer is a very simple one to a very simple question. I'm not particularly fond of that answer, and I would like to showcase other answers where I put more work in.
Note that GitHub suffered from the same problem where there was a lot of noise in people's profiles, and they implemented Pinned Repositories, a great feature in my opinion.
