Open Letter to Facebook: Erase My History!

Dear Facebook,

I went to watch The Social Network and as much as I understand some parts are fictional, and other parts dramatized, I liked it very much.

It has been great having an open platform to share information with other "friends" however close or distant, since the day I became a member in 2007.  While I haven't been the most supportive when it comes to playing your game application partners' games like Farmville, Mafia Wars, etc. - I have blocked these applications and sometimes along with the "friends" who sent me those annoying requests - I have been a very active and supportive member of facebook in terms of updating status, checking newsfeed, making comments, updating my relationship status, and of course uploading thousands of pictures of mine.

Yet, the more information I have accumulated on FB, the more difficult it is to manage accessibility of such information by my new "friends" - especially potential suitors.  My very "rich" dating history has always been transparent to older "friends" but certainly my new "friends" don't always need to know so much about my past - one can map out my dating timeline with key names & faces & significant events.  (Now this is an idea for a fab app if it's not already available).  

I would certainly appreciate one of the below functions to avoid such future embarrassment:
(1) A simple function to search one's all past interactions with a "friend", from pictures tagged together, to wall messages exchanged, to comments on pictures, pictures of that "friend" posted by  and vice versa - and SELECTIVELY REMOVE SUCH HISTORY from he/her FB page.
(2) To keep all such history but either
a. Block one's history with a certain "friend" from a new "friend".
b. Block one's new "friend" from seeing any of his/her past information/ postings/ tags before a certain date in his/her life.  (E.g. before the day she broke up with an ex.)

If your platform is so successful in allowing people to share information easily anytime, anywhere, please also enable comparable ease of removing/blocking/hiding information we don't wish to share with everyone.

Your consideration is much appreciated.

PS: I believe dictionaries should give "friend" a new official definition - Facebook has redefined the meaning of friend to any contact one establishes as a connection on Facebook.

Sincerely,
Tea Yee
