After reading the article it is light on what the details of the suite actually was. FTFA:
"District Judge Denise Reilly threw out four of the five statements, saying they were either opinion or the comments of others on the blog. With respect to the remaining statement, the jury agreed with Clark's claim that Hoff had committed "tortious interference" by meddling with Moore's employment. Clark pointed out to the jury that Hoff, in a later blog post, took partial credit for Moore's firing."
So most of the charges were dropped by the judge, and it seems the last was about the blogger actively trying to get the other guy fired. He claimed to be telling the truth, and the other guy says, um no that ain't so.
Looks like the jury decided that he wasn't all the truthful? Hard to say when little is given as far as evidence one way or the other. Perhaps the jury was right.
