Feature Request for activities.list and .get :

There are quite a number of content sources now that embed a rich display widget in posts. For instance, a Soundcloud URL in the text auto embeds the soundcloud player in the post. However only a few of these (like Youtube) result in object.attachments[] or an embedded widget in object.content This is particularly annoying when the post consists of the attachment and no text since in the API it looks like it's a null post with no content.

I'd like to see three enhancements.

1) There should be a generic approach here. If a URL automatically generates an attachment in the desktop web display then it should generate an Attachment object in the API return

2) Object.content should do what the documentations says it does. The HTML-formatted content, which is suitable for display So it should be close to a straight representation of what the desktop Web shows for the post. Now perhaps this would require a new field (eg object.contenthtml) something like what Atom does with <content type="html">. 

3) Dealing with the null case. It shouldn't be possible for the API to return nothing for that post. At the very least the content should contain the URL of the shared link.
