Actually, I didn't come up with my 'upside vs downside analysis' here on HN : it's how I've been explaining why I'm in the US to anyone who asks. I've had far more nods of understanding from the people back home (in the UK) than anywhere else.
More than anything it gives me hope to here that. I've been relying on last.fm to count as the defacto startup of choice for too long. I hope it all works out for you, whatever you're doing. If you need an upvote somewhere or a celebration of what you're trying to achieve, please send me an email.
