Google Reader's new friendz feature is the worst thing that has ever happened to me in my life! I think it's worth pointing out that when we don't like software, people can turn around a fix quickly. I think Paul's take was best: had Google made it work correctly from the start or soon after launch, people wouldn't have adapted to the broken-ness of the software.
I just like noting things like this to file away in my own development experience. Of course I'm joking about it ruining my life, but I did hide all my friendz; if I want to know what they're sharing I'll read their weblog.
