Does Entrecard helps

My question - Does Entrecard and dropping cards helps? I've been trying for the last few days to do card dropping (Entrecard) and trying to understand the whole process and idea behind it.

I think I like it! It's a great idea of getting free traffic to your website, making some friends, learning some tricks from other bloggers but I know that I have to plan my time as well. Entrecard is very .... like a gambling but here you don't spend real money.

It brings good traffic, people leave comments without being forced into it. (I mean various contests.....where there is a comment but it's empty with real content.... you probably know what I mean.... we all did it).

So what is next? I'll be trying to figure out how to earn more bucks. If you are first time here and you don't know about my 10000 $ blogging plan click here and about my inspiration - Bloggernoob.
