the price to 0.003 bitcoins, which is kind of lame.

$1.68 wont stop luke Jr editing out comments which were factually true, but didnt meet with his opinions (eg: litecoin, which he hates)
Cant say im a fan of many altcoins and never saw the point of litecoin. Not sure any of it belongs on the bitcoin wiki, though maybe one page for the unique features of altcoins would make sense. Namecoin being one which is entirely unique and well deserves a page of its own.
