Re: Don't you think that merit system is like avoiding new comer in Bitcointalk?
I am very worry about new merit system. This is like killer rules for newbies like us. As i know that if somebody gives merit rating only then our rank will grow. Without getting merit from someone we can't rank up from jr member. So, who will give us those merit rating? Is this rules for avoiding new comers in bitcointalk? I am truly feeling too bad. 
In answer to your question and looking at your own post, looks like it does not stop newcomers
There is no reason to feel bad, you can become junior without merit, and it only takes 5 to 10 decent posts to rank member, which anyway would take a couple of month to achieve I think. Frankly, if you have not made 5 or 10 decent posts in a month you should feel bad about it.
I think that merit now is a bit "expensive" but in the future it may be granted for posts that are just a bit useful and targeted to the issue.
