We've split pages (into 2 pages max) for about 7-8 years now. It did immediately increase pageviews, but our goal was also to have more control over the layout of the first page. We wanted to expose certain feature/related links without having them buried at the bottom of a 10,000 word article. Splitting long articles into 2 pages gave us the best of both worlds. Minimal clicking (since we only have a maximum of 2 pages) and we get more pageviews, and we get to expose more content that may help the user further.
