I loathe policies about expiring passwords because it breeds insecurity in the manner you mention. However, my company has this same policy, not because its been evaluated as being a good policy, but because our SOX audits require it.
I have no inside knowledge, but I have generally found that things are usually not as good as people say they are, nor as bad as people say they are. Nevertheless, Yahoo clearly has some issues to resolve.
Perhaps they are wishing they had taken the Microsoft buyout offer?
I wonder what they would do to ensure a network would be available in remote or combat situations. Perhaps the investment in technology and research would benefit the private sector as well.
If enough would choose opt out (despite the obvious intimidation tactics), then the entire process would become so inefficient that an easy, efficient alternate would be provided (or the scanners removed altogether). It would likely take a majority of people opting out though.
My signature is company mandated, was done by our marketing department (along with all email signatures in our company) and includes 6 lines of contact information, an image of the company logo, and then a disclaimer paragraph (which only gets attached to external email).

He has to spend 5 to 15 minutes everyday hiding followers? Does he follow that many new people in buzz everyday (automatically or implicitly) or are they not staying hidden? That estimate seems large.
one of the early stated goals of Stack Overflow was to be a better version of Experts Exchange. It looks like they are accomplishing that goal, in terms of users switching (which of course, the graph does not prove but does seem to suggest).
Every job I have ever had I have gotten either through personal contacts or by sending my resume to a company that I was interested in. It wasn't that people were doing me favors, its just that it put me in the right place at the right time and that was much more effective than browsing online ads. I have read statistics that say most hires are made through personal contacts, otherwise known as "networking"
Valuations usually are calculated in a way to benefit whomever is doing the calculating.
