Harsh! It's not the best logo ever, but it's things like the sunburst logo that remind me that it's the work of an individual. It gives the app personality, and draws a sharper line between tools and platforms.
To clarify, the logo I'm referring to is the blurred "Newsblur" at the bottom of the website, not the sun. Judging by the OP's point about it hurting their eyes, that's probably what they're referring to too.
