>I think first publish it on your blog then promote it by submitting its link in social bookmarking, article submission etc. techniques....
It's a useless effort to publish the same article everywhere, it would be regarded as duplicate content and not taken into account for your rankings. Better keep your blog always updated with fresh and good quality content and do social bookmarking at the same time with other articles that relate to your niche.

It is an effective way to post a content on your blog than submitting to various article submission sites. And it not a right way to use blog's content to submit in article sites. No search engine likes this way and may be it count as spam.
