Six reasons why guest posting is awesome. A must read! http://internetmarketingservices.com/6-reasons-guest-posting-is-awesome/
I can't see this post and I don't know why but here is what I think about guest posting: It's definitely worth it but it's hard to do it. If you are not a famous blogger no one will publish your post. It's hard to get my post published on Mashable or some other popular website because I started my blog 2-3 months ago. And if you get published somewhere, you will get published on some low traffic blog and that's not the point. You should get a lot of traffic and reputation by guest posting and you will get that very hard if you are a beginner. You should write quality blog posts for your own blog first, and after you become a pro writer, you will start writing posts for other blogs. Just work hard and be smart and you will achieve success as a blogger.
