The options to filter or search information when viewing Content in my Profile, in my opinion, has much left to be desired. From what I understand, Authored and Participated filter information based on whether I participated or initiated the thread. Likewise, Following applies to all threads and all posts of spaces I follow. Drafts seems to be the only option that filters my own information as I cannot see other people's drafts.
I find the current filter options are usually to broad and hence more than often not useful to find information. What I usually require is to filter information that I posted, or that someone else posted. Currently I see no way how this can be accomplished. It would help to have a couple more filters or categories, such as "own posts" and "posts by others"
