Bought it a few years ago... and I wouldn't recommend it. It was created in a pre-iPad/iPhone era and it's not comfortable to use from anywhere else than a PC.

Agreed. I moved to Fever ages ago, never looked back. Works great on my iPhone too.

Combined with Instapaper, I have feel like I have achieved the perfect reading workflow.

Quicktime required for the demo video? Seriously? Sorry, I don't have quicktime installed on this computer, and the days of me installing local applications/plugins to watch video online are over.

Is this any good? Do you have the ability to customize it yourself?

PHP and MySQL, yuck!
