There are two kinds of “funda” posts.
1. I want to put my ideas across on a particular topic. So I write this long essay and the comments will mostly be “CP” (class participation). It’s like a lecture.
2. I want to “introduce” an idea/topic and encourage debate/discussion on it. Here, I expect longer and richer comments, many of which add much more value than the original post. Maybe something like a case discusssion!
Of course given that I like to sermonize, I tend to put more type 1 posts than type 2 posts.
