That site takes its Doge price from http://www.cryptocoincharts.info/#jump-doge-btc (and seems to underquote it too) and the Bitcoin price is taken from bitcoinaverage. Anyhow, this a great first effort. I'd use it to tweet out on @dogeprice as I am doing already with @btcprice. This is a really hot market at present. It's also full of opportunities. Dig in Shibes.

This is amazing. This page should just be the top link on any Bitcoin discussion: "Guys, guys, guys, I'm feeling really bullish on Sexcoin. Does anyone have the Winklevoss' phone number?"

... hah, link that to mining costs and make your miners automatically switch currencies as the market fluctuates.

Unsurprisingly, this has been done.

(Guess it goes to show there are no new ideas left in the world...)

this site sort of already does that
