Also, keep in mind that some people don't have enough time to rank their accounts here, I'm talking of business owners and individuals who have talents but want to provide their services here. That's why there's a copper member.
Also, the copper member membership is there for those who do not want to open new topics with "Newbie how to..." guides in order to earn some merit and upgrade their rank.
But you are aware that when you acquire the knowledge first, it will be easier for you to make money, with the information we acquire here is what will give us the insight of making money, I'm just capitalising to whom that introduced people here, because I believe if the information they processed to their brothers and lovely ones is to go and make money in bitcointalk, without signatures campaign many people will be offline in bitcointalk, let their interest first be in having the knowledge of bitcoin at hand not to immediately earn money, that's my point
In fact, the biggest problem here is that everything is quite transparent, so everyone can see how much someone earned this week in the signature campaign. Imagine in the offline world, a company that pays salaries in front of everyone (employees, associates, casual passers-by...) and clearly emphasizes how much someone earned. Crazy, right?
