The POF one tickles me, i love the whole approach.

The genius in it is not spending untold time and money building the latest whizz-bang responsive gui, or never getting launched because the "web scale" back end isn't the worlds most perfect design yet. It's all just hacked together organically, with the simplest, path of least resistance choices taken at every stage.

I love that this succeeds, i love that it's not over ambitious, i love that it costs the owner minimal maintenance time.

Hats off to that man!
