although ezine is great, it takes time to get your content to get approved. if you have patience. i also tried squidoo. wetpaint. hubpages. .. there is probably more. sometimes its better to sprinkle your content all over the web.
It's true that squidoo, wetpaint and hubpages take up a lot of time. I tried making a squidoo page but with all the customization and editing that needs to be done, I lost my zeal and went over to submit my articles to link directories instead.
Of course if I do get a little more time (and enough effort) I'd be using these extensively also.
One of my Favorites is http://www.ideamarketers.com/ They have an easy to use web base and you can easily syndicate your articles. They are also not so critical of article substance.
I think everyone has their own place to go submit articles. You can use places like ezine articles and go articles and some even use a submitter like article marketer. People have their own success using these and som don't. The choice is your to test which is best for you.
Ezine article is the best place to publish your articles, it can drag a good amount of traffic to your site. But usually ezine people takes around 7 days to review and publish your article.
