To the person who started this thread... Use everything! Don't limit yourself to only two... Visit www.SocialMarker.com and set up minimum 5 accounts on the popular bookmarking sites such as digg, stumble upon, reddit, technorati etc... and submit each post through this service as soon as you publish them... Also, once or twice a month, write an article with 3-5 variations using an article spinner, and submit these articles to high ranking directories such as ezinearticles, goarticles, articlecity etc... all pointing back to your site in the resource box... Don't forget to do your keyword research, and include your targeted keywords in your post titles, and throughout the content... Hope this helps!
Just as I mentioned earlier, traffic from Digg is very hard to convert to money. In fact, all posts that go on top of Digg are news related and amazing bits. Since this thread is about marketing and not just traffic generation, I prefer Ezine.
I use ezine extensively which works out very well, but never tried digg for posting articles. Looks like I should try that
