Go Magnus!
The spur for live rating:
On Magnus Carlsen page Nov 04-07:
"Rolfo: <of course, the above will change during the last 3 rounds>, that means frogbert, you are in position to keep us updated on rating changes "live" :)
Even if you don't, I think FIDE's 3 month update is slow..
The person who would maintain and publish dynamic updates of top 50 players will gain some interest, I'm sure"
Then Hans Arild Runde aka frogbert took the challenge. The rest is history.
Runde's live rating:

By now the instantly update is done by

And FIDE now updates 12 times a year! And even rates rapids and blitz' :)
