This is true but elance offers a monitoring software as well. Both companies show a steady growth but odesk is way more successful in the last two years. On top of that elance started the market entry in European countries. However odesk seems to grow twice as fast as elance. Is the outsourcing market in USA and Canada still growing that fast? Seems that odesk is stealing from elance AND is drawing from network effects or a different market effect which could be a indicator that it is a winner takes it all market
