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.
