I can't tell if it's my monitor, or something else. But yeah -- that, the logo up top, and the News Ticker all look like they have some soften / blur effect applied.
Everything else looks fairly sharp though. the grey bar on top, the headlines below the ticker, etc.
I don't know nearly enough about CSS to dig it out - I get lost in all this wordpress Luminous and Gradient stuff if I try to peek around in Dev mode.
