I was wondering what all the possible types of posts I can expect in a feed. The documentation at http://developers.facebook.com/docs/reference/api/post/ mentions that the type field could be link, video, and photo, but that's clearly not a comprehensive list. I know that there are at least the following possible types (because I've seen them): status, link, video, photo, checkin, note, swf, and music.
But are there more that I'm missing? Is there a complete list of these types somewhere?
I know of someone who says that they've seen event attendance and friendship acceptance posts in their home feed (from /me/feed), but I can't seem to recreate that. Are those also types of posts that I could expect?
