Everytime I logged in I see 28 people online at most which is a big improvement from 12 people online. Which means BitDice's signature campaign os working for their site. Also seeing that it has reach 40 people online makes me more happy as we are helping BitDice to be recognize by more people.
How do you know if the increased number of online people is the effect of the signature campaign? Sure, it may be the effect of the campaign but it may be caused by something else. I do believe bitdice not only rely on the sign campaign to get more and more players, they might have some other advertising ways out of this forum.
