#1. When I write for publication in a book, journal, etc., I go over it again and again, I show it to others for their feedback first, I chew over it for a long time, tweak it and tweak it, etc. When I write on a blog, it's not possible to write with that kind of care. That's a problem with blogging in general.
#2. I open myself on my blog for a frank discussion of my view on a variety of sensitive issues, and I do it under my own name. This is even though I am a target of attack for many people, of all sorts (which in one case led me to having to make a police report). But many of the people who comment and argue with me do not do so under their own name. So they get to try to catch me out/ insult me under the safety of anonymity.
The combination of the above two is what really frustrates me about a comment on an earlier post, by a person who does not give his full name, and who makes a comment about my not giving my opinion on something. I've been quite busy (baruch Hashem) and have not had the time/head to formulate a proper response. Sure, I could toss something out off the top of my head. But why should I? Since I am the one putting my name to my comments, shouldn't I have the right (even the obligation) to refrain from responding until I have time to do so properly?
