Check out the cool application available at MyGamercard.net. It allows you to show all your hi-scores from Geometry Wars 2: Retro Evolved on your blog, forum posts, or wherever will accept the codes.
As you can see above or long term on the right side of the screen, I am no GeoWars 2 expert, but I certainly enjoy the game. It is also one of the most addictive games in my collection. How high are your scores? I would like to see how I compare.
