I just visited your site to see how you present the list of 666 different coins. I only see the usual list of 20 or 30 coins in the menu. Where are the rest?
And when I select CLAM -> BTC it doesn't show me the price. It keeps showing the LTC price, even if I wait for the animated bar thing to fill up a few times. There's a 404 error in the console, and some text about it having loaded the development version of the page. Not sure if relevant:
Edit: oh, 666 *pairs*. That's just 37 coins then (37*36/2 = 666). "now able to allow trading between ALL coins" is misleading. There are more than 37 coins. There are more like 666 of them... I guess you mean "allow trading between all 37 supported coins" - that would be much clearer.
Edit2: the menu does indeed list 37 coins, but
https://shapeshift.io/about only lists the fee for 32 of them (BTC, BLK, BTCD, CLAM, DASH, DGB, DOGE, FTC, GEMZ, LTC, MSC, MINT, NMC, NXT, NVC, NBT, POT, PPC, QRK, RDD, XRP, START, SJCX, SDC, SWARM, UNO, XMR, XCP, VRC, BTS, BitUSD, USDT).
