Stumbleupon's Members Now More than 7 Million

Remarkable now everyone can notice that this social network is growing even faster than what we expected. StumbleUpon itself has clearly claimed the exact number of its total users. It is really a very great deal for Stumbleupon to achieve this stage without any promotion but can get about 50% more than Twitter. What will Twitter do to deal with this situation?

Accordiing to alleyinsider, Stumbleupon can make money more than 10 million each year. Of course the profit is expected to increase as more members have registered.
