Following "juci" now - poor kid, I know how it feels to talk into a void...
Hysterical... I thought about following Juci until I saw those updates!!
She is not really flooding my message stream, though. And the updates are kind of cute ("eating cake") - not so much different from the average tweet? I just subscribed to Jimmy Wales' updates and he wrote "dinner with friends".
And btw - I believe the scalability issues are platform / design based. All of these improvements are just that, improvements. The system needs to be built to scale first
