I like how PSN is now linked to our playstation blog accounts and that we can now see the status of our friends from the PC. How come we can't send messages from the PC though?
Kinda what happens when you make things up as you go along.
Sony's online plan for the PS3 has been slowly taking shape for a long time. They didn't really go into this online thing with a solid idea on what they even wanted the Playstation Network to be or do. We've seen things get added and ideas change on a regular basis.
Hopefully someday they'll have this 'what should be basic' feature available.
