Version 1.8 (Change-Id: I52672f9fffa92ea48e110f9ebb419dd0fbdc1f6f/gerrit #184858) of SocialProfile finally adds the ability to select to whom a profile field (such as "Hometown" or "About me", etc.) is visible. Sadly the UI is somewhat broken right now (live demo on Labs) if and when the right-hand field is an <input> instead of a <textarea>, which is the case for the main Special:UpdateProfile page, where the "real name", "email address" and such fields are located in. The subpages, such as Special:UpdateProfile/personal which do not contain <input>s aren't really affected (at least not as much as the main special page).
