More questions and a book

I took a look at some posts from the beginning of this blog and I saw a post with this question: why do people write blogs?

I still don't know why, but I have more questions:
- why do people start blogs and abandon them? (they are just too lazy?)
- why do people read (lots of) blogs?

I'm reading a book by Neagu Djuvara - Amintiri din pribegie (Memories from exile - although "pribegie" doesn't mean exactly "exile", but I don't know how to translate it). This guy lived in exile during the communist era (from 1944 to 1990). He returned immediately after the 1989 revolution and is an active and well known public person although he's over 80 years old. He spent about 20 years in Niger, so the book gives an interesting insight into African affairs among other things.
