Tradeleaks was brought out by Kogan (the OZ electronics seller) to whistleblow on trade secrets in Australia. Unfortunately, while it's an interesting idea, there is no quality control and as you can see people have been posting all kinds of things. It's an obvious publicity stunt to cash in on the wikileaks trend but at the least most of the threads are amusing. As it's hosted in Australia, expect Tradesecrets/Kogan to be legally threatened soon and the site taken down. In the field of nonsense, there were some interesting "leaks" that applied to some bargains and shops.
Disconnecting from Foxtel - Apparently threaten to cancel and you will be given freebies. Not really much of a secret but interesting to here that it's an internal policy.
Coles Accepts refunds from Woolworths products-Interesting, probably more of a staff can't be bothered thing.
JB Hi-Fi-Talks about headquarters set cost price, buying in packages better, and what commissions they get.
Telstra - Supervisors Encourage You To Re-Contract Customers Who Decline-Not suprising
Just a warning, some of the comments are probably NSFW as it is not moderated.

Its a really cool site, I just wish there wasn't so much junk on there.
