There is no such word as a blunder in blitz.

The title of this post comes from a comment on the Chessvibes site concerning the current World Blitz Championship. Certainly at the top level, you might see less blunders than your run of the mill blitz event, but of course the quote is referring to the fact that blitz is pretty much "anything goes".
This hasn't stopped Carlsen and Aronian putting there stamp on the event, scoring 10/14 at the end of the first day. The other big talking point (at least amongst the chattering classes on Chessvibes) is the performance of Hikaru Nakamura. Having held the top spot on ICC in Blitz for a number of years he was considered one of the favourites, but a horrible 1/5 start left him in the middle of the field at the end of day 1.
Results from this 3 day event can be found here. There is also live coverage of the games, but given the time limit 3m+2s, it is kind of hard to follow everything at once!
