Helium and Associated Content are best sites to write an article. Are you a writer? is writing your forte or skill? Do you have passion for writing something?
Then Helium and Associated Content is the right site for you. Not only will you earn money, but you will gain confidence in writing. Although I do not recommend this site to Asian members since they restrict the sign up for US residents and other countries who's first language would be English.
Anyway, why not try the site and see it for yourself. I have lots of friends who can testify that this is the right site for them and they earn.
