I think it could be a good idea to have the ratio of your answers with 0 votes vs. your answers with 1+ votes on the profile page.
It could give further insight into the quality of a persons answers.
I'm generally thinking of this because I see quite a solid amount of people with relatively high reputation who have 1000 answers with 0 votes (I'm just making the numbers up of course ...) and 100 answers with 10+ votes.
I'm not saying this is bad, I'm just saying that if we can see the 'answer ratio' we can maybe make a slightly better distinction between people that just answer everything to try and 'grind reputation' and people that actually put time and thought into their answers.
This could however lead to people being afraid to answer questions because they might loose ratio...
