koan: "click here to read the rest of the article" is one of my "pet peeves". It will certainly decrease your bounce rate, but that isn't the correct user engagement metric to be using in that case. There are probably three relevant user engagement metrics that you should be using on article pages:
1) percent of users that read the entire article
2) percent of users that click to other parts of the site
3) percent of users that convert (click on ads, sign up, purchase, etc)
For SEO, Google probably cares most when users return to google and click on something else or refine their search. Your attempt to decrease bounce rate would hurt the metrics that Google uses and actually hurt your site from an SEO perspective.
