Nice! Simple and straight-forward, love it. The Bio is a bit awkwardly phrased. Not the content itself but just how it's structured and present for example, the jump from Ballet and Dancing to Arts and Design is abrupt.

So only advice would be to clean up the language a bit, maybe but otherwise awesome.

Definitely agree with this being made open source.

But in regards to colour, One of the tent poles of the site right now is the simplicity of design and colour, so rather than matching the source site colour to the item itself on the list, and possibly making the thing annoyingly colourful, I'd suggest maybe just highlighting the source name in the item with the matching colour. That way the visual cue is still there but it's not overpowering.
