I didn't use Twitter, and I won't use Facebook either.
What else did this grand, 200mb update bring? The major change it mentioned was: now it displays your photos in a matrix form, instead of in a vertical list. YIPPPEEEEE!
Another thing I noticed was that all the people on my friends list have changed to different colors. Now you can not only have a profile, and a message, and an avatar, you can make your PSN name box have a color! YIPPPEEEE!
Not. What a waste of 30 minutes.
