Yes — agreed on multiple levels. And while we’re at it, why not also the following:

A “used to date” feature

The other day Geanna and I positively wracked our brains over whether or not ______ had dated _______ while we were in high school. After 10 maybe 15 full minutes we were forced to give up and then Geanna later had to ask him if he’d dated her. Wholly unecessary use of time and pride.
In my ideal world this feature could be manipulated by anyone who is your friend because no one would willingly load their past relationships, but then when that backfired on me I’d regret it.
Anonymous posting
There are a LOT of things I want to say/do/post on the book without my 1X1″ self associated. A simple “go-ghost” feature (profile pic appears as a black box? pixelated? bearing the sign of a pirate?) would give us all the opportunity to keep friends and enemies in check and engage in some very advanced prank warefare.
Lies associated with “blocking people”
Right now when you decide to ignore a friend request nothing at all happens leaving the person on the other end to wonder if perhaps you just haven’t checked that particular inbox in 5 months. I feel it be better for everyone involved if your hitting ignore prompted a drop-down menu of lie options. “Jessie recently experienced identity theft and as such is not currently accepting friends” or “Jessie is trying to manage her Facebook-life balance and right now needs to keep friends at their current number.” Yes everyone knows what that really means, but it’s better than hearing nothing, forgetting you sent the request, and going through the whole rejection cycle again 5 months later.
Friends prioritized by significane
I think it needs to be clearer who we’re actually friends with and who we’ve accepted on account of we need to find out exactly when they finally get engaged. Frankly, people are looking — that’s why we have the Facebook in the first place — and I don’t want them thinking I’m just as close with X as I am Y just because they’re both in my NYC network. I won’t propose how this can be solved because I’ve gone far (mean…) enough, but color coding and a star-system should probably be involved.
Ability to block news feed items based on topic
If I could have eliminated all news of ________’s wedding prep for the one year prior to the blessed event I’d be a more stable person. That said _______ also sometimes posts other interesting info I’d want to weed out from the updates on her dress fittings. I prefer, as a general rule, not to take the bad with the good. A simple subject sieve application would solve this.
And the ultimate — ability to see who’s look at your profile
I know for a fact that they have this feature inside “the system” so it’s only a matter of time before we can all know just how many (or few…) times certain people click on us. Once this finally happens the world will be changed forever. That is not a dramatic statement — it is the truth.
So Mark — what’s it going to be? Are you just going to keep changing the size and shape of our profile pictures until we all jump ship for Twitter or are you going to man up and give the people want they really want — advanced ways to behave like elementary school students on the Internet.
