Are all the articles about the same topic?
I think it would be better if you are working on 10 different websites with 100 related articles in each website, instead of one site with 1000 articles about 100 different topics. Does this make sense?
Also, if you are targeting each article to a specific keyword, in essence, you are doing SEO.
Final note, I have heard/read somewhere that the Google spiders have a hard time following/indexing sites when they get too big (more than 250 or 300 pages of content). Not 100% sure about this, though.
