I agree. I also think that for your own sake, there is good reason to exercise caution about what you put on your blog, even if like me you're writing more for your own satisfaction than out of a desire to inform or educate others. For instance, if a person writes about what ugly, foul-smelling, complete and utter muppets their line managers are, and they are easily identifiable from their blog to people who know them, and they have identified the company they work for on their blog, then it only takes one troll to look up the company website, find those managers' email addresses and send them a link to the things that have been broadcast on the internet about them. This will not lead to a favourable performance review. It's important to remember the distinction between what one would write in a private journal, what one would discuss at home over a cuppa with close friends, and what one really wants to broadcast to the world for anyone to read and use as they will.
