I know once the ads started on the site, the traffic here grew quickly. The more users on the site, the quicker you can gain points.
An example is when I reached the million point mark, there were only 6 other users, including you, who had reached that milestone. It was an awesome achievement and something to strive for. It usually took several months or more to get there, but it can actually be done in only a couple months if working at it.
Took me 10 months to reach one million, another 10 months to reach 2 million and if I reach 3 million sometime in January, it'll be another 10 months.
