Thanks for that information, that's interesting. Either way, I thought it was an interesting article, and it was well written too. I also agree with the core point that growth without retention is meaningless. I suppose I just take issue with the term 'viral' here, although your point stands even with business-to-business: if you've had a sudden influx of customers, then you'll need to fight to keep them rather than just considering them an unchanging constant of your business forevermore.
