Oh now this is cool, Yahoo! has seen fit to reformat everyone's profiles, but in the transition has reset every last one of them to totally, unabashedly blank.
What really impresses me is that Yahoo's statement about the botched transition acknowledges that they could retrieve your data, but politely decline to do so unless you force it by going through their general tech support gauntlet.
Not much else to say here. Basically, if you want an example of how not to transition your user base to a new version of your platform, check out the new Yahoo.
