I use SEO Linkvine to place lots of "spun" articles on unique blogs all over the Internet. Here's the one fact you need to keep in mind. Massive article marketing is a good thing if you use all unique content. Massively spreading the same articles all over the Internet is, while not useless, not very effective. Google ignores duplicate content. You need to either write a lot of articles or use something like The Best Spinner to "spin" them into unique articles. There are also a few article writing software packages out there but I haven't tried them. I'm too good a writer to need them. But they might be helpful if you aren't a writer.
