I’ve noticed something over my years as a blogger. People like to comment on subjects that I will call “theological” (for lack of a better word), but not “exegetical”. In other words, if I write a post on the Trinity or Calvinism v. Arminianism it is bound to receive a response. If I write a post on text criticism, translation, exegesis of a passage, or some sort of comparison (like the similarities and/or difference between how two different Gospels tell the same story) it is less likely that there will be many comments.

Why is this? I’d guess familiarity. Everyone knows something about the Trinity, but not everyone knows something about the Synoptic Problem or the use of the Hebrew Scriptures in the Pauline epistles. This makes the most sense to me as an explanation. If someone wrote about Christology in general it invites a wide array of contributions, but if they wrote about the Christology of the Pastoral Epistles or the Christology of the Cappadocian Fathers then this demands interaction with more particularization than the open format where everyone and anyone has something to say.

Do you find this to be true? Why do you find yourself interacting with some blog posts and not on others? What motivates you to comment or not?
