I have heard that developerworks does pay pretty decent for external authors. Now in the Lotus community there is this "Best Lotus Blogger Award" voted by the wider public. For developerworks Java there are often article series by Rick Hightower and other folks from the wider Java community. I allways found those very interesting.
How about institutionalizing the blogger-Domino relationship a bit by offering the paid authoring of a 3 part series of articles to the winner of "Best Blogger Award" on developerworks/lotus aka notes.net. Maybe some newbies or platform switchers catch interest in the quality stuff that person publishes on a regular basis, who would otherwise not? Maybe the blogger can use the paid time to provide even better content?
