I tried loading up
www.pandora.com, a flash-based jukebox that recommends music based on descriptors applied to a song you choose (i.e. Tosca results in "thin ambient synth textures, trippy soundscapes, and modal harmonies"), but it freaked the

out. It went to the website, loaded the graphics and showed the flash-based loading bar, but when it reached 'complete' it just refreshed the page, repeated the process, and sent me to the home menu of the browser.
The time before that, I linked to it through my Gmail so I could send myself a bunch of quick links to try out on the Wii, but it was even more finnicky. I clicked the link to Pandora, it immediately gave me a "this protocol is not supported", I hit OK and it went on loading the site anyway. It eventually froze up.
I don't think the Wii likes Gmail much. Clicking on an e-mail to view gives not 'click' sound, as it doesn't interpret it as a link, and it then takes a couple extra seconds to load the e-mail.
I just wanna send myself .swf links to try out, since they ought to resize for the screen automatically, but I've only tried sending them through Gmail and they simply won't work.
