Every social site with “friends” functionality needs a per-friend “snooze” functionality, along the lines of:
When I’m logged-in, silently hide all new [tweets | journal entries | photos | links | foo] by this friend for n days
Whether it’s necessitated by an overblogged conference, a messy breakup, an adorable puppy, that new Nikon, or a bout of non-specific update mania, we all need a break from the onslaught now and again. I shouldn’t have to (sigh) “de-friend” someone to realize that break.
And, yes, you may most certainly snooze me, too. That is the whole idea.
