Simplify your user profiles by removing fields your users don't need...
I installed this plugin as an admin tool for hiding certain fields my site does not need at all, and to hide other fields I do not want users changing all on their own. This plugin lets you hide user-profile fields or bring them back out without losing anything in them.
You can minimize the profile down as far as only username, email, and change password.
In my Twenty Twelve Child Theme, these user-contact fields still show and cannot be hidden:
Twitter username (without @)
Tom has told me the additional support for hiding those fields will be added within less than a month (1 - 3 weeks), and he has already been quick in releasing an update for one very-minor bug.
