You are right about this. But some people may fustrating at first. Actually the introduction of rc have really helped both in reducing spamming messages and many more. I guess if investing in time, it will takes months to stand on your own. But well, as for me that i have no money, i have no option than to invest in time by making valuable comments on people post and to create an interaction also. I will hope this pay me at the end. Thanks for replying to my comments. This post was also great
