I quite like the "people reached" metric on the profile page for stackexchange users, one thing that intrigues me is which of my questions that are reaching people (are they ones I'm proud of, ones that were simple one-liners to an easy question, etc...), I used to open answers that I suspected were on popular questions to see how many views each question had but that has now gotten worrisome with my having 200+ answers. This should be true for the average active user as well.
So, my feature request would be the request to sort out my answer history in terms of "view count". The metric already exists and I don't think it would be to hard to sort answers based on that metric. To specify, the option to sort by views would be near the red box here:
Edit: After a fruitful discussion with Martin in the comments below, the "people reached" metric is much more constrained that the view count on questions you've answered, but I assume that the algorithm for the "people reached" is break-able into a per-question basis that would make this feature-request feasible.
Using the existing data from only the raw viewcount on questions is not enough, since for example, you could answer a question after it has garnered most of its views but it would still rate as the most viewed answer in your list.
