Oh, something almost comprehensible from a surprising source.
However, I think you need some ABC in corporate security.

Why in the world would anyone put 'confidential' information in their status?
On an Internet wide service?
If any corporation anywhere allows their employees to use yahoo for corporate use they soo deep in the yoghurt that this is the smallest of their issues.

And so is anyone engaged in corporate security.
Many companies use various 'messenger' software internally, but only on secure corporate nets, against secure corporate servers.
Connecting to any form of external platform is 1, against corporate policy, 2, denied by firewalls and proxies.
You can of course bypass that, but that is equal to industrial sabotage and leads to 1, you're fired, 2, you're sued for damage.
There's tons of security issues with every online 'communtity' service.
But they're personal security issues, not a corporate security issue.
And as stated, if an issue like this would ever touch corporate security than that corporation is soo deep in yoghurt that this would be the least of the problems.
