One caveat about posting a lot of content to the forum: it's good to be mindful of "horizontal" versus "vertical" space on the forum. If I broke my tutorial on Petri nets into too many small articles, it would take up a lot of horizontal space, and could dilute the main view of the forum -- and many people might not be interested in this topic. So I took a cue from Paul's approach, which is to concentrate the content into larger "vertical threads."
There are no rules about this. It's just something to be aware of in a social setting like this.
