Here is a suggestion for next time; check btcwisdom with a different exchange when you see a flatline. If you pick BTC-e instead of bitstamp you will see life.
Implying there was ever any life on BTC-e.
Actually there used to be over 10k people/bots there trading. So yeah there has been life on that site, even if it doesn't compare to the bigger companies I still see that as a pretty large trading organization (or used to be).
