In Profile view we currently have the # of likes a member has... It would be nice to also see # of topics 'Answered' being a tally of the number of times a users post has been tagged as the 'Best Answer'.

Fantastic suggestion!

We really do want to expand on the 'Best Answer' system in 4.0 so that it ties in with reputation, etc. We held off for 3.4 as we didn't want to add anything destructive that would require a fair bit of refactoring.
