It is much easier to say something on here, facebook or Twitter because it can just purely be the thought you are having.

Once you want to translate that into a blog you really have to flesh it out and ideally read other sources and reference them. We you don't have to but I feel less comfortable just putting something down as opposed to really getting into the idea. Unfortunately all this takes time making me less likely to start it in the first place.

edw519 has mentioned this a bit, very prolific poster that is very well regarded on HN and has a lot to say but struggled to really do it in the blogging medium.
