So with my admittedly meager research (reading Slashdot and other sites), I can't figure out if the Wikileaks people are good guys or bad guys. Which is it?
You can't figure it out? You like governments and corporations around the world keeping secrets from citizens at their expense?
The only problem with this years Nobel Peace Prize is that Wikileaks was a better candidate for it. (Tianmen Square was limited to China, while Wikileaks has the potential to change the world.)
For Wikileaks to possibly be in a "bad" category, it would have to do something bad. By what twisted reasoning can you find anything that Wikileaks has done somehow fit into the category of bad? The only people who could possibly suggest that there was anything bad about Wikileaks are bad people who don't like their secrets revealed. They make up lies about the consequences of revealing the secrets. They even have resorted to a smear campaign against Julian Asange. But at the end of the day, you can't find any shred of anything that Wikileaks itself has done that could be in any way construed as "wrong" or "bad".
On the side of "good" it is almost a stupid question. They do the job of reporting what governments are too cowardly and craven to face the public on. They are the megaphone for a conscious' of the myriad whistle blowers who see corruption all around them and are exasperated by the fact that nothing can be done about it, short of this desperate attempt to let the world know what is happening. Wikileaks makes it possible -- it gives whistle blowers the anonymity they need to execute their exposures.
Your question is hardly recognizable as even remotely rational.
