This interesting thing to note about this news is that according to the graph, Bitstamp didn't really rise, so much as Gox has actually fallen to Bitstamp levels. I will however say I'm happy to see this, especially given the fact that Bitstamp is currently the only Ripple gateway with any real liquidity. Unless the rumors of Gox connecting to the Ripple network are true of course.
How does one invest in Ripple, anyway? I'm nowhere near as sold on it as you are, but it's so cheap I'm willing to take a shot.
