I've been reading some reviews and 2010 predictions from various people (like Kunstler, linked to previously) and I thought it would be a useful exercise in humility to link to a post where I was quite spectacularly wrong: World War Three by Easter 2006! I pursued the thought here and elsewhere.
I suppose one of the good things about a blog is that it becomes a record of such things - which means that I have become much more circumspect, and that is healthy.
I still think we have entered into a great dislocation though ;-)
PS feel free to add in any that you remember. 9/11 I covered here.
