Is there any way to see how my comments have been voted on? For instance, you can sort your answers by votes, but is there a similar feature for comments?
For up to the minute data, use the API:
api.stackoverflow.com/1.1/users/[YOUR USER ID # HERE]/comments?sort=votes&min=5
(change the minimum value if necessary, this finds all qualifying Pundit comments)
See http://api.stackoverflow.com/1.0/usage for all of the other items in its bag of tricks.
