I have never bothered to change my livejournal's layout despite using it for five years. I don't even use myspace unless I get a message saying someone wants me on it, so why would I bother?
It's bad enough making layouts for snowy-day
YEAH THANKS FOR APPROVING MY FRIEND REQUEST LIKE SIX MONTHS AGO.
I use the default m-space layout. My LJ's been green and white for about four years and I haven't really had the drive to change it.
