An interesting article, expanding from means of disagreeing to methods used I'd add a few observations. There's the shotgun refutation where a poster quotes almost every part of a post with a weak disagreement making responding to every point almost impossible and there's the essayist who writes a needlessly long response making finding and responding to their central point much harder. Essayists often use deliberately ambiguous passages so they can claim you don't understand rather than explaining clearly.
Another internet or more general debate strategy is to refer to the voluminous works of others as if you've read them and behave as if your opponent cannot respond until they've read every last page, often with little attempt to explain or apply the supposed arguments and facts that come from those sources.
Most internet posters are unable to state things clearly, partly because people are taught to obfuscate and because they're embarassed to put their points in view so nakedly.
