As a member of your target demographic and someone who considers herself to be a ‘cute geek’. I really dig the layout of the site, and the ability to change the colors/background to my liking is super nifty.
However.
That pink background is awful. The teal isn’t to great either, but it didn’t make me immediately want to close the browser like the pink did.
I like pink, but the shade you’ve got here is just to hard to look at on a monitor. I couldn’t even focus on an articles I was so distracted. You need to de-saturate your color scheme a little.
Also my feminist side is mildly offended that the background with squares in it is named ‘Kitchen’. But I am probably being over sensitive about that one.
