Articles are not worth the trouble IMO. Here is why, the content gets picked up and replicated who knows where, then the pages with the data go supplimental in most cases and then gets dumped from the index. C'mon, you need to be smarter than that these days - this little gimmick worked for a couple of years but it's way past it's used by date. I would take a recip PR5 or 6 over from the trusted site any day of the week over an article link on the back end of some site that is using article directories to gather content. All of the SE's are on to it - Keep your content and setup an RSS and do some 2.0 stuff and get people to link into your site.
