This is awesome! I had been wanting EXACTLY this for a long time now. I'm not a UX / design person, but I appreciate the impact that it has. Normally I'll just look at what others are doing and implement my own variations on it, but it's difficult to find small examples, and exploring stuff in websites such as dribbble is tedious.

Most of those designs look the same to me. It's the "clean", minimalist, flat, vibrant colors, boring fad. It's sad that creative artists are not allowed in professional design.

The 404 error pages are rather amusing:

^ Tags should really be you know, actual tags, not tag ID's though, how are search engines supposed to know what each tag is outside of the URL (which is the easiest indicator I would assume). Only just noticed this about tags.

Love it. I would love to have this for mobile apps too.

Also check out http://Crayon.co to find designs sorted by industry.

very nice! how is the content sourced and picked?

Now... take some advice from your own UI inspiration and don't do something as insane as adding a white 90% opacity overlay as you're scrolling and mousing over things. Extremely jarring.
