Well, I don't think there's much to add to the summary ;) I have no idea since when this happens, but google already has it in its index (i.e. if you search for something amarok-like you get this page as result).
akregator.kde.org is maintained outside kde sysadmin control. I will move this bug to the akregator component.
Not sure why akregator.kde.org points to kollide.net. Would it be possible to make it redirect to userbase.kde.org/Akregator instead ?

DNS change is in, once that propagates, it will be redirected as requested.
