I have a set of pages in user profiles which, depending on the user's actions, may or may not have any information on it. It's essentially a feed of the user's comments. Some users add comments, some don't.
Google Webmasters has marked the pages without any comments as 'Soft 404s'. Now, these pages aren't 404s as they are meant to exist, but they don't have any data (yet). What is the correct http status code to handle these types of pages which exist, but may/not have data on them in the future?
