I've been reading this : (it's Long, by the way!)
...they like the idea that there’s a place where a record of their existence is kept — a house with an always-open door where people who are looking for you can check on you, compare notes with you and tell you what they think of you. Sometimes that house is messy, sometimes horrifyingly so. In real life, we wouldn’t invite any passing stranger into these situations, but the remove of the Internet makes it seem O.K.And this is from another one of her blogs
..The will to blog is a complicated thing, somewhere between inspiration and compulsion. It can feel almost like a biological impulse. You see something, or an idea occurs to you, and you have to share it with the Internet as soon as possible. What I didn’t realize was that those ideas and that urgency — and the sense of self-importance that made me think anyone would be interested in hearing what went on in my head — could just disappear.
When you write about things as they’re happening — which is what most people do on blogs — you lose perspective, or rather, your perspective shrinks, so that only a tiny slice of your reality gets recorded. The cumulative impact of several months’ worth of posts can lead to an entirely different conclusion than a few snippets taken out of context. This is the danger of blogging and also its seductive charm. It’s so easy and fun to report on your current state of mind and your opinions, especially when you have strong feelings, and strong feelings are also fun to read about.
