CoinChoose - find best coin to mine and best exchange rate

[sal002]

I had this in the alternative currency sub-forum, but thought i'd also announce it here.  I launched a site that shows the best crypto coin to mine at any given time, plus the best exchange rate (into BTC) for such crypto coin linked to the exchange.  A 12 hour graph showing profitability is available along with an API to get all data from the site.

It is located at http://www.coinchoose.com.

Comments / suggestions / blinding flashes of insight are all welcome.

The value of some coins jumps up and down during the day...it would be nice to have a chart, based on the average values from the past 7 days.

Great site btw, thanks!
