Questions API/Operations

I'm looking through recent additions to Facebook Graph API and Spring Social API. Questions Operations has been added in https://jira.springsource.org/browse/SOCIALFB-37. From the source code it looks like Question class stands apart from Post class hierarchy. It's true that fields in Question and Post are quite different, though Graph API returns questions as well within /posts endpoint. This leads to empty raw "Post" instances. Wondering whether it's reasonable to combine them into common hierarchy or update feed operations to support multiple base classes somehow. Thanks.

Good point...will look into it.
