You'll find a lot of the devs at #vWii on Efnet. That's where I hang out.
Don't join there unless you are willing to help though. No discussion of piracy. Helping out doesn't necessarily mean you have to have hacking or reverse engineering skills. You can always be available just for running tests.
wiiuhacks (for my opinion) is the "evolution" of wiihacks channel (exist a site called like this, talk about wii homebrew/loader/ wii modding ecc.. that site not allow piracy and is online today.
the_randomizer, is very simple... not go to that channel, i use irc from ages, and i have take a ban "only" because my kline finish with .it!!! some channel ban if u write "CIAO" ecc...
