Just a bit feedback on the blog: The background image was very distracting for me. My eyes were always wandering off from the text. Not sure if that's just me or if others had that problem too.
Coderwall forces you to upload an image, then it "hipsterizes" it (their words, not mine). From what I can tell, this involves significantly reducing the size of the image, increasing the saturation and local contrast, and then stretching and blurring it.
As a photographer, this is quite annoying, because it's hard to predict what something will look like. I'll try to find a photograph of mine that'll stand up to being "hipsterized" better.
Had similar problem with a site called TVCatchup. They stream free TV in the UK. Their player sits in the middle of the page and that is surrounded by an advertising border. Nothing else on the page of consequence. What I found was that I found it very hard to focus on the player in the middle. Often I would get a headache watching. Told the admins, who didn't want to know. Basically I got an angry "Foxtrot Oscar". Ended up using an ad blocker until they found a way to defeat that. Now I don't use the site any more.
Completely off topic, but TVCatchup provide an XBMC plugin which completely avoids the advertising they add. No idea why, since it presumably destroys their business model, but it's great.
