1. For some, their blog is like an art gallery: things that are shown are expected to be either accepted as a whole, with everything they contain, or not accepted at all, even if they contain something a visitor doesn’t agree with or approve of. But it’s not even quite like the traditional type of art gallery. The main idea is, you let a piece of the author’s mind inside yours. You don’t interpret it. You don’t adjust it to yourself. You don’t process it in any way that could alter it. Needless to say, any side thoughts don’t do much help in this case.
2. Often, a post is intended as a finished thought, and thus any comment can be an insult, since it accuses the author of not fulfilling the main objective: the very fact means someone still has something to add to it.
3. I have very specific views on some subjects, so explaining them in response to one or another post may get the author even further from understanding whether I’m in agreement with him/her or not.
4. Finally, in 99% of cases I’ve got nothing worthy of saying to say. I believe that communication must be meaningful, though some may beg to differ. At least I believe that such belief keeps you disciplined when it comes to communication and makes you strive to get better and better at it.
