Implied: there were some rocky bits in the intervening 7 months.
I'd love to hear about those! This certainly isn't a judgement on their success---scaling to 24/7 in a month is impressive even if there remained bugs to work out. (It's also not a judgement of the OP, which explained what it set out to explain, i.e. the initial one month.) So I guess, consider this a request for an interesting follow-up post. :)
Based on what they told me, it sounds like the scheduling was the hardest part. Second hardest was probably finding the right phone system that worked perfectly for them.
If you have any specific questions, I recommend you tweet http://twitter.com/jessemaan directly...I'm sure she'd be happy to answer if she can!
As it's not it would only be a waste of time as people calling as Google "customers" would ask about their search difficulties or Gmail formatting concerns.
