Very good point, I have seen similar things with other startups. The good news is that the traffic jumps, but it is also true that if you do not have virality built into your system, you plateau after a jump like this. The key is to jump on opportunities, but it cannot be a strategy because sometimes it works and sometimes (most times) is does not, not everybody wins the lottery. Building virality into the system works though, so it can be a real strategy: figuring out the roadblock in the acquisition of new users, and then removing them, or even better find something that would really benefit your users within their own ecosystem that you can offer at no cost (you do not want a system that digs a hole in your finances as you get more customers, unless you are backed by a VC who thinks this is a great way to do business).
