Well for the first time for one of my websites, ive submitted articles to directories, and i know its a long process of getting links etc, but can honestly say i can see it working well already. I only submitted about 6 articles in my niche to two article directories ezinearticles and articledashboard, and i can see slight traffic increase from other websites other than the directories, and now its coming upto 1000 links Hopefully will increase more as time goes on If you havent already, i recommend submitting some articles
You can also submit to goarticles.com , searchwarp.com and articlealley.com. My articles often get picked up from these sites (besides ezinearticles.com) and they do send some traffic too.
Articles are surely a great way of promoting a site and getting links. But can you clarify if you've got 1000 more links.. or the total number of links to your site are 1000 now ?
Try http://www.articlepostrobot.com . You can post article to about 289 sites by clicking ONE button ONCE. You don't have to click 'submit' button on each article site one by one which takes a long time. The site list is at http://www.articlepostrobot.com/sitelists.htm which covers most high page rank article sites. Also, use Article Post Robot, you can make each article site have an unique version of your article. So, you do not have to worry about 'duplication penalty'. you can request a 7-day demo by sending an email to help(at)articlepostrobot.com temp
