Do You Write for Ezine (or similar)?

I have been adding ezine articles every now and then as a way to get a few more readers and to provide some useful information about crafts.

My latest article is about kirigami : http://ezinearticles.com/?Simple-Kirigami-Patterns-for-Beginners-and-Children&id=6917098

Have any of you written ezine (or similar) articles? How many of you have positive results from writing articles and how many think it’s not worth doing?
