Anyone having/had troubles with Facebook today? I'm getting a white page now, earlier some of the messages being sent flashed up late - who said MySpace had the biggest problems? 

Oh well...

it went down for me for about a hour, not really bothered tho.

Mine was down yesterday too, it just showed me messages from several days ago and everything that was more recent vanished. I "fixed" it by logging out and in again on my phone. The annoying faces at the top of the mobile app (my story?) disappeared too, so not all bad.
 

It was down on and off most of the day for me, yet worked fine at times on my mobile.

I didn't know what to do for the time where it was down, not that I'm that social on FB but its just reinforced my new found love for Twitter.

No idea, I hardly use it during the day.
