Article submission still works in 2013.
It is useful to get website traffic to your website by giving your website link in the articles.
Just found an awesome article directory at google.
i submit all my articles to this directory because Its pagerank is 2 and it is dofollow seo friendly article directory.
The site link is http://largearticle.com
I have found that when i publish my article at http://largearticle.com my article gets indexed within 2 minutes in Google.That is very useful if you want to index your website in google.
Though they have some guidelines to become author but they are very easy and article gets approved within 2 days.
You will get a pr 2 d0follow permanent backlink for lifetime. and best of all it is free.
i found it useful so i thought why not share it with my friends.
